At the video rental store, the customer that returned a DVD case reeking of cigarettes and full of cockroaches. I had seen the customer before and always read the notes about the latest gross ass thing they'd done that flashed up on screen when serving them because all the other staff hated them and would write these complaints. Despite that I didn't really remember them particularly or have much of a run in with them.

I happened to be the one on shift when they were to discover they'd been banned though. They tried to pick up some movies to rent and I had to explain that I couldn't rent to them because they were banned. They asked why and I told them that it says here you returned a DVD case full of cockroaches and they responded indignantly "What!? Is that IT!?" They definitely weren't denying it and seemed very surprised this was a bannable offence.
