When I worked at a supermarket
Some twat decided to park in a disabled space (when there was at least half the car park free) and when I went to confront him, he looked at his mate, laughed, and pretended to hobble into the shop.

I went to get one of the "Don't park here you able-bodied person" stickers and stuck it to his wet windscreen, right in his field of view.

It was a paper based sticker, so he spent the next 30 mins trying to scrape the sticky bits of soggy paper off his screen!
