Not in Quebec City they don't. Haha. I've never been to a ruder place in Canada. They get pissy with you if you speak English (understandable) but also get pissy with you if you try to speak what little high-shool French you know (wtf is that??). It's too bad, because it's also the most beautiful city I've seen in Canada.
Montreal is another story though. People there are usually very nice, with the occasional jerk.
I've noticed that the press lately has been using the word "Quebecker" a lot. Not sure if I like that one. It looks ugly and a tad vulgar somehow. "Quebecois" is much nicer sounding.
...i have rarely encountered rudeness in quebec (except the drivers, but that's another story entirely).
however, i think it is very, very important to respect the french language and culture. all it requires is a "bonjour", or a "merci". almost all "quebecers" appreciate and respond to this show of respect in kind. at least, that has been my experience.
i have a love affair with quebec and the french people that spans the sixteen years i spent there (1970-86). most of my family now resides there, and i have a grandkid who, at 2 1/2, is already fluently bilingual.
