Man, that’s hard. When I go there I try to follow etiquette closely, it’s their custom and I want to follow it, and the woman may have been a bit of a Karen.

However, tap water should be free. Anywhere. Maybe I just hiked a mile to get there. Maybe I’m just thirsty. 7 euro to drink water is simply extortion of your tourists. If that’s etiquette then it’s wrong.
