There was something like this happen at my daughters school. Some inconsiderate twonk parked on a residents driveway to drop off his little cherub. When the owner returned she parked up where she could and put up the security pole so it blocked the car in. She refused to let the car out and in the end the police had to be called. I didn't stick around to find out what happened but it was funny and maybe will teach the driver some manners
