When I was in Prague (long time ago, was there for about three years, and was squatting most of that time)... I often encountered the idea that I had to be slumming it, because all Americans are rich. Which often justified their ripping me off. Or just them wanting my attention.
The attitude was most embodied by one of the anarchist kids in the squat when he said, "I know America isn't all 90210... is it?" with a look of genuine wonder.
