We sat in the car another 20 minutes and waited. Out came this guy that looked like a personal trainer. He came jogging up to his car, chatting on his phone. He saw the note, screamed “Oh, S"№IIIIIIIT!” Then he spent the next 20 minutes going over his car, inch by inch. Rubbing every speck of dust or dirt. He was still looking when we left.
Nothing harmed, no damage – just a lesson (hopefully) learned.
to be fair it's not nearly as much fun beating someone with a nightstick if they are already in a wheelchair.
