17 American Cultural Differences I Noticed While Living in the US

---

Across the years covered by this post, I spent three months in upstate New York, six months in southern California, one month in Chicago, one month in Nevada, four months in San Francisco, two months in Texas, a month in Louisiana, a month in Oregon and two months in Maryland. I also drove through 25 states and later lived in New York City for two years. That adds up to more than four years of local life, not just a quick holiday, and I've kept returning to the United States since.

Even with all that time, New York, Texas, Oregon and Louisiana are not interchangeable. These are 17 cultural differences that stood out to me, filtered through my Irish and European habits. An American from another region, or another European, may have a completely different list.

I genuinely like the United States and have made lifelong friends there. Cultural friction can still be funny, frustrating and useful to talk about, as long as one person's reaction doesn't get dressed up as a verdict on an entire country. If you enjoy that side of travel, you may also like my 29 life lessons from travelling the world.

1. Directness can feel very different

The first difference I felt was conversational directness. In Ireland, and among several German friends, blunt advice can be a sign of closeness. In the United States, many people I met softened criticism or waited to be asked. I initially read that as evasiveness, while they probably read some of my directness as rude.

That isn't the same as saying Americans are never honest. My friend Karol gave me clear, useful notes after I delivered a TEDx talk, while several other people simply told me it was brilliant. His feedback caught me off guard precisely because I'd grown used to the softer style.

I still value constructive criticism, but I've learned that being frank and being kind aren't opposites. The real skill is knowing how much directness a particular friendship can carry, rather than assuming one national style is honest and the other is fake.

2. “Awesome” does loads of work

On my earliest visits, I kept hearing awesome for everything from a life-changing achievement to confirmation that someone had received an email. I was used to the word carrying much more weight, so the American version sounded wildly overenthusiastic.

Eventually I realised that it often functions as friendly acknowledgement rather than literal awe. The same goes for answering “How are you?” with “Great!” when the question is really a greeting, not a request for a health and happiness report.

I still don't love the word, mind you. When every sandwich, meeting and minor plan is awesome, I have to listen harder to work out when something actually is.

3. Smiling at strangers follows different rules

Americans I met abroad sometimes complained that nobody smiled on Prague's trams, while I had the opposite reaction in the United States: strangers smiled at me far more than I expected. At first I wondered how I was meant to tell a polite public smile from genuine delight.

That was me misreading a convention. In some places, smiling is a routine sign that you acknowledge another person and mean no harm. In others, a smile is reserved for a warmer moment, so it can feel more significant when it arrives. Neither version is automatically false.

I still prefer not having to look cheerful while I'm doing a crossword on public transport, but I no longer treat a stranger's smile as evidence that they're lying to themselves or to me. It may simply be the local equivalent of saying hello.

4. Tipping culture

Restaurant service in the United States felt much more attentive than I was used to. A server might check in several times while I was eating, whereas in much of Europe I would expect to call them over when I needed something. Neither system is inherently rude, but the American rhythm took adjustment.

The bill was the bigger shock. I wanted the menu price to tell me what I would actually pay, while the local convention expected me to add a tip. That expectation also has real consequences for workers: under current US federal rules, an employer may pay a qualifying tipped employee as little as $2.13 per hour in direct wages if tips bring the worker up to at least the federal minimum wage, although many states require more.

I still prefer a system where the employer pays the full wage and the listed price includes the service cost. Until the system changes, though, a traveller's dislike of tipping isn't a reason to withhold money from the person serving them. Learn the local norm, budget for it and complain about the structure rather than punishing the worker.

I wrote more about my early confusion around tipping here.

5. Prices before sales tax

Tipping was only one reason the displayed price often wasn't the amount I handed over. Sales tax commonly appeared at the till rather than on the shelf label, which is especially confusing when you come from countries where consumer prices normally include tax.

State and local sales-tax systems really are complicated. The IRS notes that rates and even the tax base can vary between local jurisdictions, sometimes within the same ZIP code. That explains why a single national calculation isn't possible, but it doesn't make the visitor experience any less strange.

I still wish each shop would do the local calculation once and show the final price to everyone who walks in. A label that says $10 when the customer cannot actually buy the item for $10 feels incomplete, even when everyone who lives there knows the convention.

6. Advertising felt much louder

One evening on an early visit, I watched an episode of House on American cable television. I had mostly seen US programmes online without adverts or in Europe with different commercial breaks, and the frequency caught me completely off guard.

Every few minutes the programme seemed to disappear into another burst of sales copy. Prescription-drug adverts were especially memorable: smiling people on screen while a fast voice ran through a list of possible side effects. Streaming has changed how plenty of people watch television since then, so this anecdote belongs to a particular era of cable rather than all American media today.

The broader style still struck me in supermarkets and in Las Vegas, where casino layouts, lights and sounds constantly tried to hold my attention. I admired the skill while disliking the feeling of being worked on. Other countries advertise aggressively too, but the American version I met felt more direct and relentless than what I knew from home.

7. The urge to upgrade

My original example here was the annual rush to replace one working Apple device with a slightly newer one. Naming old model numbers only dates the article, but the habit itself is familiar well beyond Apple and well beyond the United States.

I benefited from it in Austin when only the first iPad had been released. The day the iPad 2 was announced, I saw around 20 new Craigslist adverts per minute from people selling the original model. One man sold me his two-month-old iPad and Bluetooth keyboard case for a quarter of the original price because he wanted the newer version immediately.

I found that wasteful, but I'm not outside consumer culture myself. I buy good phones and laptops, and I've occasionally bought things I didn't need. The difference that bothered me was treating a marginal upgrade as a necessity, particularly while telling me that travel was financially impossible. That is a behaviour I saw, not a uniquely American personality trait.

8. Stereotypes travel badly

I had versions of the same conversation on the east and west coasts, in the Midwest and in the South:

“Hi, I'm Benny.”

“Awesome! Where are you from?”

“Ireland.”

“You guys certainly know how to drink!”

“Actually, I don't drink.”

“You're not really Irish then, are you?”

It happened often enough that I could see the punchline coming. A few people cheerfully told me I was the only Irish person they'd met, immediately after telling me what Irish people were supposedly like.

Other questions and claims I personally heard included:

• Surprise that Ireland had airports and that I hadn't arrived in New York by boat.
• Insistence that Ireland was part of the United Kingdom or the Commonwealth.
• Questions about whether I had checked my car for IRA bombs while growing up.
• Surprise that an Irish person knew more about technology than they did, as if we were all potato farmers.

Those encounters were frustrating, but they weren't proof that Americans are ignorant. They showed how easily stereotypes survive when someone has little contact with the place they're describing. Europeans do the same thing to Americans, and this article's old version sometimes did it too.

9. “I'm Irish” can mean different things

When I said “I'm Irish”, some Americans replied “me too!” and then explained that an ancestor had left Ireland generations earlier. In Ireland, I normally use Irish to mean nationality or where someone grew up. In the United States, it can also be shorthand for Irish-American heritage.

Once I understood that language difference, the conversation became much easier. “I'm from Ireland” conveyed what I meant more precisely, while “I have Irish heritage” made the other meaning clear when that distinction mattered.

People are entitled to care about their ancestry. What still makes me roll my eyes is treating it as genetics that determine personality, such as saying an Italian ancestor makes someone passionate or an Irish ancestor makes them good at drinking. Heritage can connect you to family history without turning millions of living people into a character type. If that connection inspires you to learn more, start with the Irish language rather than a drinking cliché.

10. ID checks and drinking laws

I was refused entry more than once because I hadn't brought my passport to a bar or nightclub, even though I was clearly an adult. I also saw people in their sixties asked for ID. Carrying my most important document somewhere it could be lost or have beer spilt over it felt ridiculous.

The national rule itself is clear: the minimum age to buy alcohol is 21 in every state and the District of Columbia, according to the National Highway Traffic Safety Administration. The details of acceptable ID, public possession and open containers vary, so the old joke that a brown paper bag makes an outdoor drink legal was never useful travel advice.

I still find the contrast with European drinking rules strange, particularly because I don't even drink. The practical lesson is simpler than the rant: check the local rule before going out and bring ID that the venue will accept.

11. Religion was more public in some places

I grew up in a religious Irish town and went to an all-boys Catholic school, even though I'm not religious myself. The cultural surprise wasn't that Americans believed in God. It was how openly religion entered ordinary conversation in some of the places I stayed.

In my social circles back home, faith tended to be more private. In parts of the United States, Jesus could come up more in a week of small talk than he would in a decade among those friends, and I never quite knew what response was expected.

That varies enormously by family, region and community, just as it does across Europe. My discomfort was about unfamiliar public language around faith, not a judgment that religious Americans were less modern or reasonable.

12. Big chains were hard to avoid

In several places I found that the easiest food and shopping options were large chains, while independent businesses were clustered in particular neighbourhoods. That made spontaneous wandering harder when I didn't know the city.

One day in downtown Chicago, I walked for an hour looking for an affordable bite to eat and ended up at Dunkin' Donuts. Chicago obviously has loads of excellent cheap food, but I wasn't in the right part of the city and didn't know where to look.

My old conclusion blamed corporate competition for a lack of small businesses everywhere. That was too neat. City layout, commercial rents, local knowledge and my own poor planning were all tangled up in the experience. The useful observation is that I couldn't rely on the European habit of walking until a small café appeared.

13. Many places were built around cars

This was the most consistent practical difference I encountered. Outside a few dense cities, everyday life often assumed that I had a car. Shops, affordable restaurants and supermarkets could be kilometres apart, and public transport ranged from workable to barely useful for the trip I needed.

My experience wasn't imaginary: the US Department of Transportation has described the country's heavy reliance on car-dependent, dispersed development, including neighbourhoods built without pavements and with limited public transport. That still doesn't make every American city the same.

I liked Austin, but while living just outside the centre I had a stretch of my walk with no pavement. In other cities I could be the only pedestrian on an entire block in the middle of the week. San Francisco and New York were obvious exceptions in my own stays.

I didn't get my driving licence until I was 28, which many Americans found hard to grasp. Once I rented a car, everything became much more convenient, but I also felt as if I were using my feet mainly to work the accelerator. For a visitor who likes exploring on foot, that changes the whole texture of a place.

14. Life could feel rushed

In some restaurants my food arrived within minutes, appointments started exactly on time and conversations about work moved quickly to goals, growth and the next opportunity. Coming from places where a long meal or a late arrival was less remarkable, I felt the pace immediately.

Punctuality and ambition are not defects. They can make things happen, and I benefited from that energy. The difficulty came when I absorbed the idea that every spare hour should produce something measurable.

During one period living in the United States, I became more stressed than I'd been before and had to rebuild my work-life balance. That is my story, not evidence that Americans as a population are sadder or more stressed than everyone else. It did teach me that I need some unproductive time in my life, wherever I live.

15. Money entered the conversation more often

I met people whose bank balance, promotion or business opportunity seemed to occupy most of their attention. Some earned far more than I could imagine and still sounded unhappy, while others assumed travel required tens of thousands of dollars. My own experience of travelling cheaply made that hard for me to understand.

I also met Americans who valued time, family, art, community and a quiet life far more than status. The contrast wasn't “Americans care about money and Europeans don't”. It was that the ambitious circles I moved through in the United States spoke about money more openly and treated financial growth as a solution to a wider range of problems.

That openness can be useful, especially compared with cultures where money is too awkward to discuss at all. I simply don't want earning more to become the automatic answer to every question about a good life.

16. Restaurant portions were bigger than I expected

Restaurant portions in many of the places I visited were much larger than what I was used to. Even a small order could leave me completely full, and free soft-drink refills made it easy to consume more simply because it was there.

I was brought up with guilt about leaving food on my plate, so this went badly for me. During one stay I put on loads of weight by treating the serving as an instruction to finish everything. The restaurant hadn't forced me to do that, and the old version of this article was too eager to blame the country.

I eventually learned the obvious local solution: stop when I'm full and take the rest away. A generous portion can be tomorrow's lunch rather than a challenge I have to complete.

17. “America is the best”

The claim that bothered me most was American exceptionalism presented as fact. I met people who worried about whether I was safe in South America while barely questioning the risks or limitations of their own country.

My own feelings of safety often depended on whether a street was busy, whether I understood the local cues and whether I knew where I was going. I sometimes felt safer on a lively street in South America than on an empty block in a US city, but that anecdote cannot rank whole countries by danger.

For a long time, the United States was also the only country where I'd had something stolen, an experience I wrote about in this post. That didn't make it uniquely unsafe any more than one good trip would make another country universally safe.

There is no objective best country. Patriotism can mean loving your home and wanting it to live up to its ideals; nationalism turns that affection into a claim that other people and places are inferior. I'm happy to hear that the United States is brilliant for someone without being told it must therefore be best for everyone.

What I love about Americans

A list of cultural friction is only half the picture. There are plenty of things I love about the United States and the people I've met there:

• Particular people. I've made lifelong friends there who don't have equivalents anywhere else in my life.
• Work ethic. Some of the hardest-working people I've met are Americans, and I've seen that energy turn ambitious ideas into real projects. The trade-off matters when work consumes everything else, but the drive itself can be impressive.
• Finding your people. Tools such as Meetup made it remarkably easy for me to find groups built around specific interests, especially in large cities.
• Conferences and conventions. The scale and variety gave me conversations I would have struggled to find elsewhere, from blogging and travel events to a Star Trek convention.
• Landscape and variety. One country contains an extraordinary range of climates and scenery. The Grand Canyon remains one of the most impressive sights I've ever seen.
• Openness and diversity. The United States gave me friendships and conversations across backgrounds I might never otherwise have encountered, and people repeatedly welcomed me even when I was blunt about what confused me.

The old version ended by saying I was blunt because I cared enough to be straight with Americans. There is some truth in that, but caring doesn't excuse turning a pattern I noticed into a fixed trait of an entire population. Honest comparison works better when I own the limits of my experience too.

Some of my best friends in the world are Americans, and I keep returning because the country still surprises me. If you meet me, you can disagree with every item here. Just tell me directly!
