I have also been sitting in my car when morons park next to me and open their door up into my car. They don't put a note on my windscreen or apologise. They just walk off. I had one guy open his door up into my car and I got out and said "Oi, wtf you doing?" He just walked off so I wandered around and looked at the damage. I looked at the guy by the shopping centre door watching me. I held my car key up and pretended to drag it along the side of his car. I didn't actually touch his car but I made it look like I was keying his car. He went inside and didn't come out for over an hour. Then I left. I should have busted his windscreen. Dent and scratch my car.
