Had 3 or so americans in the train. The kids screaming and even came up to my ear to yell in it! They didnt have their kids under control.

Or american "woo!"-girls in the inner city talking so loudly you could hear them 2 streets down about how "its so primitive here.", we "should have a parking spot for them in the center." So they "dont need to walk so much".

There are lots of respectful people tourists. But i have yet to meet a respectful tourist from USA
