We had a friend who would play Metal when the ice cream store he worked at was closed but the customers were lingering too long. It generally worked, as he was immune.

I introduced my local restaurant owner to Mongolian Techno and the late night bar flies and some of the kitchen staff have never forgiven me. He won't admit if he plays it for himself, or because of them :)

I play disco music to keep the kids off my lawn.

A live music venue near me plays this when it's time for people to GTFO:

I was at a coffee shop once that was playing metal while my writing group was meeting there and I just thought they had excellent taste (it was not near closing time)
