I was getting lunch at a fairly popular shopping area with off-street parking. It was tough finding a spot, but then one opened up. When I get back there's a tow truck blocking about four spaces, including mine. Engine is running and no driver in the cab. I just sort of stand outside and maybe hope the driver notices. I don't see any activity going on that would require a tow truck, and I'm thinking the driver just left to get lunch or something. Then I get in my car and honk the horn a few times. At that point I'm frustrated and figure I'll take a photo of the truck's operator and state license number if I feel like complaining to the owner/manager. Eventually the driver gets there and moves (blocking another set of parking spaces). Then he motions to me as I leave and I'm wondering what his deal is. He asks why I took the photo. I say I was ticked off about being blocked and was thinking of filing a complaint, and if he thought I did anything illegal. At that point I'm not going to complain, but it did cross my mind to have some proof my car was blocked along with the phone number and state operator's license.
