Get ripped. Step one is going to be talking to the office (Em, can you do that when you get home? Take the license plate of the car parking there with you when you go.) and asking them to resolve it. If not, find out what towing company they use there and call it in ourselves. The guy has been asked not to park there any longer, yet he decided today to do so. So, want to play that game? Okay...you can pay for the towing. Moron.
