Pissed me off, and I stewed about it the whole time we were shopping. When he was still parked there when I came out, I decided to get spiteful.
I found a piece of paper, and left a note on his windshield. It said:
SO SORRY – I did not mean to scrape your car with my wheelchair. I would leave my contact info, but you were illegally parked, blocking my van. So good luck buffing that out!
to be fair it's not nearly as much fun beating someone with a nightstick if they are already in a wheelchair.
