UPDATE:
Okay so I left work and went to the car to take some pics and see what it said.
Luckily it was only a warning, but still annoying as hell because I think that's a bunch of BS to call someone on. Truck in front of me also got one too so luckily I wasn't singled out. BUT the one guy (in original pic) ALLLLLL the way at the end parked clearly ONLY in the no park hash zone got NOTHING! WTF?! left me scratching my head. Guy was clearly parked in hash mark zone since lunch when I noticed and as I left 4:30PM NOTHING!

Seems they like to pick and choose, that or they don't care how u park on the back end.
