I'm French and born in Paris, and I find most of French people very impolite (I live more like a Japanese, with the "fear" to disturb order and people), so I don't complain when I am in another country.

But the only country where I could live is Italy, because they have "real food".

I really suffer with the local food when I'm abroad, and as far as I know, all my friends suffer as well. My wife is Russian but lives in France for many years and she has the same reaction with food in other countries (except Italy!). It's not arrogance, it's pain and a feeling of eating dirty things !
