Person wants to go to Christians to get pizza. No parking around. Decides to weigh the risk of parking in 7-11 knowing they could get towed. Decided to take the risk anyways. Did not avoid risk. Towed.

I understand the tow truck driver is an asshole and predatory, but that part doesn't even matter, all of his asshole-ness and bullshit can be avoided pretty easily if you just don't take the risk. Once you take that risk, the fault is all your own.
