I did that to a truck once. I had been waiting at a gas station for this spot for like 10 or 15 minutes and this truck pulled in from the other side. I honked and raised my hands and said hey I've been sitting here waiting and the lady ignored me, got out and went inside the store. I drove around, got out and kicked that large of a dent in the side of her truck bed. I got in my car and drove away.
People need to know there are consequences for being an asshole. It could have gone badly for me but it didn't. She probably didn't even realize till her husband saw the truck...lol
