stupid people

so today I get to work, park in a parking spot that is unmarked. I just got an e-mail that states I need to move my vehicle or else I will be ticketed. mind you I work in a large building, Corporate security is getting ticked cause I parked in an area that carpool only people can park. Well...Since I have handicapped parking plates I should be able to park anywhere there is a handicapped parking spot. But apparently that's not true.....Hmm....now i'm a little more then irritated.....
