Not to get things completely off topic, but yeah... I've experienced that too. More with the Dutch than Germans though. Some Germans can be snooty, but I think by-and-large, they're mostly just misunderstood by non-germanic folk. As for the Dutch, Amsterdam's been a s**t magnet for sooo long so no big surprise there.... but on top of that I think they're tired of Canadian's (but probably mostly American's) going over there thinking that they owe us something for Liberating Holland.
Once transiting threw Schipol airport, I was going through security and a Canadian Lady was about to miss her flight and said so to the Guard manning the metal detector... the Guard blew up and started beratting the lady saying things like "You canadians think you're so great! You are all the same... you all think we dutch owe some something...blah, blah,blah!" LOL! I think she was having a bad day
