What's a moment of culture clash you've experienced while traveling?

What have you been playing lately? Discussion about video games and board games are both welcome. Please don't just make a list of titles, give some thoughts about the game(s) as well.

This is a monthly thread for those who need it. Vent, share your experiences, ask for advice, talk about how you are doing. Let's make this a compassionate space for all who may need one.
