With the return of mass U.S. tourism in Europe, there has been renewed chatter on social media about how American tourists stand out. After more than four decades of travel in Europe, I’ve accepted that I will never completely blend in. However, I try my best to avoid some of the typical “tells” that out me as a North American.

Here are some of the usual things that out U.S. tourists when they travel outside of the U.S..

1. Speaking loudly, especially in public places
2. Being very friendly and chatty with strangers
3. Smiling a lot, even at people they don’t know
4. Wearing casual clothes like jeans, t-shirts, sneakers in more formal settings
5. Wearing baseball caps
6. Leaning on things or against walls
7. Using American English phrases and slang
8. Asking for ice in drinks
9. Tipping generously in countries where it’s not expected
10. Saying where in America they’re from rather than just “the US” when asked
11. Having very straight, white teeth
12. Carrying water bottles everywhere
13. Using a knife and fork in the “cut and switch” style
14. Wearing university/college apparel
15. Being direct in communication style
16. Expressing enthusiasm openly
17. Making small talk with service workers
18. Wearing shorts in urban areas
19. Asking if places take credit cards
