Oddly I was just leaving Montreal when the flight attendant gave me a copy of the "Post" with a blurb of that incident on the top of the front page. My experiences in Montreal aren't bad, there are a lot of folks who speak a lot of languages other than French, and English for that matter. Try heading up to the nether regions and many folks don't know a sniff of anything but Quebec French, no wonder the the Germans could park their U-boats in the St Laurence, take the dinghy to shore and swig beers with the locals during the war, they had no idea a war was going on.
But while I'm anywhere in Quebec I am constantly addressed in French so I started answering, "Я не понимаю", pronounced Ya nih pahneemahyoo, or "I don't understand". Flusters the heck out of them. Or else the Newfie phrase, "Поцелуйте мою задницу", pronounced Potselooeetye myoo zadneetsoo, or, kiss me arse. At least I'm trying to learn another language, and one that will probably be more useful.
