I've been to Paris recently for a 3 days tech event. I would say that in my experience it is the French people that are often arrogant in that they get pissed / make fun of people who can't speak their language. A friend of mine that was with me and can speak French to a decent level had troubles even ordering stuff in a bar because the girls working there didn't make the effort to understand beyond his foreign accent... and he is half Belgian.

Of course my experience is limited and of course you would expect someone living in France for a long time to learn the language, but it's also a matter of good manners. I, too, would hate to live there if my experience is the norm.

EDIT: It seems that other people had the opposite experience so take anything with a grain of salt.
