They are nothing but sharks. Watch out if you are in the Chestnut Hill area. They love to patrol that end of Germantown Ave. where all the restaurants are because you are probably eating or leisurely shopping in one of the boutiques. Remember these minimum wage fake cops have to earn their day's quota, so they are NOT going to cut you any breaks nowadays in 2013. If you happen to come upon one of the parking authority folks writing you a ticket I suggest you take advantage of the opportunity to totally vent and let the person know how you feel. Being nice doesn't get your ticket canceled. You will only feel stupid afterwards. Verbalize your frustrations. That's what I did when I got my ticket today for 41 bux. I told that lady she was a real jerk and she should get a real job--a job that doesn't involve stealing ppl's hard earnings and one in which she doesn't make ppl miserable all day long. Sure, I still have to fork over the $ for this ticket, but at least I feel like I got 41 dollars worth of curses at her. Next time I might take her ticketbook and hurl it in the sewer and save every last person who got a ticket that day some money.
