Where and when was this?

My wife works at a record store too, and he/she is right, people coming in, intoxicated, singing a song off an album they want to buy, and then stumbling out with out buying it

That never happened to me but I always wanted it to.. the closest I got were too-hip-for-thou kids trying to figure out which song fits these lyrics and UH OH! FLEETFOXES! DING DING DING MAINSTREAM ALERT MAINSTREAM ALERT! EXTERMINATE
