There are several ways you can stick out like a sore thumb when you're in a foreign country.
Here are some of the biggest signs:
1. "When Americans introduce themselves, they never say they're from America; mostly they say the state/city they're from."
2. "Saying 'Hi, how are you?' to the barista, servers, retail workers. My country doesn’t quite have that culture, so I find it really sweet."
3. "Went to Russia once, and they knew I was American because I smiled too much."
4. "The absolute fearlessness of asking anyone on the street about anything."
5. "Whenever I hear someone say 'ma'am,' I know they're American.
6. "They’re looking for a store open at like 11 p.m. Even in most European countries, stores close at like 7–8 p.m."
7. "Americans will be wearing sneakers."
8. "Trying to interact with strangers in public areas."
9. "Asking for the restroom."
10. "If you see an American in Japan, they will frantically look for public trash cans.
"The absence of trash receptacles is something unfounded in the US, and we become confused at the idea of having to hold it for extended periods of time."
11. "Baseball caps, university-spirit wear, cargo shorts, free T-shirts from events with ads and text all over them."
12. "I was at a beach where music was playing, and 'Sweet Caroline' came on. I told my sister, 'Hey, if you are wondering who here is from the US, you are about to find out.'"
13. "Handing the credit card to the server to be taken away and processed."
14. "When they cross the street, they expect cars to stop for them. In my country, the cars will run you down without thinking twice."
15. "Confidence. I have never seen someone walk so confidently in the wrong direction like an American can."
16. "I remember asking for the bathroom in New Zealand, and the lady looked at me and said, 'You can't have a bath in my restaurant.'"
17. "Extra ice in their drinks."
18. "I met a man in Turkey who was stunned when we told him we were American. He more or less said/gestured that he thought we would be fat. I doubt he had come into contact with many of us, and apparently our perception abroad is...heavy set."
19. "When they comment about the driving."
20. "If they buy peanut butter. It sounds very weird, but everyone who buys peanut butter where I work turns out to be American."
21. "I got drunk in Antwerp, and I think the bartender got a little confused because I was talking to him like we were old friends, and I left a tip when I left.
22. "People assume you're either American or 'slow' if you smile in public in former Eastern Bloc countries."
23. "They get amazed by old things."
24. "Speak English louder at people who don't speak English until they understand."
25. "I would say impeccable facial hair. Maybe they get a trim before they go on holiday, but I'm always impressed by their tidy beards and mustaches."
