Oh, well if we're also talking about IRL B&!

My friends and I were escorted out of prom for getting very bored very early and going to have a look around the rest of the campus where the dance was being held, which apparently was off limits.

And then a few years later, when I was in college, I and my group-mates were (rather forcefully) kicked out of the Gap because we were trying to do a documentary project on how long it would take to drive around town and find a complete outfit made entirely in the USA, and I guess the store manager of the Gap wasn't a big fan of this idea.
