Been in the position twice where i've caught them out in the act.. it's not the best experience LOL. Had an old guy park right next to me when there were atleast 5 car spots next to me either side, opens his door straight into mine where I could hear it whilst eating maccas in the car. Unfortunately he may of been deaf when I started questioning him and yelling because he just walked off, ended up putting my burger, ice-cream the lot all over the windscreen.. didn't solve anything though. Second, had a a kid on red Ps drugged off his head almost drive his van into my car then slams door straight into mine infront of everyone at girlfriends sisters party. This time actually took number plate as he was still driving in and out with people, other than that kicked him out of the party and restrained myself from getting violent. Best story yet, had a group of guys try rip my car off whilst I was inside parked at night. What tops it off, they had no idea I was inside.. Unfortunately not many people have respect for other peoples cars.. it's complete bull**** parking in public
