I grew up and lived in Philadelphia for 27 years. I lived on a very busy street and saw on a daily basis the blatant disregard for others in the way people chose to park their cars (i.e, parking in front of a fire hydrant, double parking in the street overnight, etc.). I have no sympathy for people who receive tickets or are towed for not adhering to parking laws.
I enjoy watching the TV show Parking Wars. I get a good laugh watching people try to explain their way out of a situation where they are completely in the wrong. I give the employees of the Philadelphia Parking Authority a lot of credit. The employees depicted on the show are just doing their job. You can't fault the PPA for the fact that people continually choose not to pay attention to street signs or traffic patterns. Sure, some of the procedures are a little ridiculous, but I haven't seen any of the employees treating the customers rudely. If anything, it is the other way around.
I find it absurd that people have written complaints about the show and the city, saying they will never visit because of what they see depicted. Give me a break! It's common sense. Read the signs, feed the meters, pay attention, and you'll have nothing to worry about. It's not that hard.
