Saw my first instance of racist behaviour today regarding this.
I live in Motnmagny Québec, 3 hours away from Montreal. There are very very few people of east-asian descent here, but there is a hockey tournament right now.
I was checking 2 boomers in, and the lady overheard an asian dad come in and tell other parents in the lobby he came back from the hospital, and his kid has the flu. This woman literally took her coat to cover her mouth and nose. She turns to look at me and I hit with a "Franchement!" (translates to a really passive agressive really!?), and she lowered it immediatly.
That was my story. She had a pokerface on and barely turned red, but she looked more insulted than embarassed, but she did put that arm down fast so she certainly realized how fucked that reflex was.
