I've smoked out a college washroom, more than once. There is a park no more than block away from a cop shop where everyone goes and tokes joints, but they don't seem to bother us.

I've sparked up in bar washrooms before. No really cared, except the bouncers. I've also smoked right in the middle of the dance floor at a bar. It was crowded and Swollen Members, a CDN hi-hop group, were playing, so I found that time to be perfect to smoke a phat bowl. People around me just laughed.
