So I'm British, work for a half-French company and have been to Paris quite a bit.

There's a recurring steotype that the French, and Parisians in particular, are dismissive of foreigners attempts to speak French if they aren't perfect, but it's not been my experience. My French coworkers are all cool of course, but even the poor baristas in Paris trying to understand my broken coffee order just tanked it and made an effort.
