It depends on the person and the region they’re from. Southerns and mid westerners are known for their hospitality. It might be different in the north or the west.
My sister has lived in Germany for many years. She said that out of all the people she knows there that have visited America, not a single one of them had any bad experiences here.
@Peaches well, I don't pretend to have a deep understanding of it since I'm, well, N. American. But I think that in places like, say, the Middle East, they would see it as making real sacrifices and taking on inconveniences.
@SW-User matter of fact, I have. And they're the youngest part of the continent. I suspect they where much more hospitable in 1975 and even more so in 1949
