I met one that was snobby, total bitch too...
But that's irrelevant, I've met a few brits, very friendly, not as many jerks, it seems.
now Germany, I've a friend who went to Germany, said he got spit on several times by different groups of Germans, they cursed at him "filty american, ignorant, arrogant, stupid" things like that...I believe him, partially because he's not a liar, and partially because there have been many many many anti-american riots in Germany in the past 6 months.
Go figure?
It's a stereotype, though.
