Oh there's a definite preponderance of certain states over others when it comes to these types of people that I've noticed. But if I were to point those out anyone on here who's from there is gonna feel personally insulted.
And yep, sorry to say, while there's uninformed tourists from every country, every time you meet one with that extra idiot level of uninformed, 9 times out of 10 they're from the US.
'I know you said you're from China, but I wanna know what COUNTRY you're from. There's countries in China like Asia, China's not a country.'
(This to a Chinese fellow student of mine.) 'Why are there no decent Mexican restaurants here when you all speak Mexican.' (To my step sister who lives in Barcelona.) 'Oh if I could go on holiday abroad I'd go to Italy ' cause it's close to Rome . ' (Someone in a chat room who promptly logged off when an Italian member tried to get it into his head that Rome is in Italy.) ' Do you have cars in Germany? ' (To me by an aupair before she visited us.) Nope, we only pretty much invented the damn things. I could fill a book with those gems.
And the number of times English acquaintances of mine have been complimented by Americans on their grasp of English, as though the word England wasn't a massive clue as to where the language comes from, the number of times someone thinks Austria is short for Australia and THEN insists on arguing the point when told it's a) a totally different country and b) they speak German there, the times I've personally been asked how long a drive it is from Europe to the US etc, the number of times I've encountered genuine surprise that European countries have all the mod cons like fridges and TV and Internet etc, with the exception of the odd Australian or Canadian that was always Americans.
I mean wtf do they teach at school over there. There's got to be some systematic issue or there wouldn't be such a prevalence that every single person who's ever worked in the tourist industry (I was a tour guide for a bit) could give you a ton of such examples.
