I've been to Paris a handful of times. It's said that Parisians hate Americans, but that's not true. Parisians hate everyone.
And as for the language ... if I went in to a cafe and tried to order in French, they'd respond in English. Go into the same cafe, the next day, try to order in English ... they'd act as if they don't speak English.
Outside of Paris, the people were friendly and lovely.
I forget who said it, but the saying goes that Paris is a beautiful city that Parisians don't deserve.
