Shit...I wish we knew how to behave better HERE.
But like another poster above me said, everyone has their idiots. Asian tourists in America are annoying as fuck. Just a generalization. Americans get a bad rap abroad, sometimes deservedly so. Sometimes not. If you act like a guest at all times, then you have nothing to worry about. The problem comes in when people travel and act like they own the place. Ignorance knows no nationality.
Sucks they are doing this, as I always wanted to go visit there. Oh well, there's plenty of other places in Europe to travel to.
