Wow, that def would've bothered me too!! I like what you said!! Sometimes the staff at the doors are lovely & other times they're on a powertrip.
I once walked out of a store (as I didn't have anything to buy), opened my handbag & stood there while the lady at the door saw I was there but kept talking to another staff member (gossiping about other staff). I got sick of waiting & they were rude so I walked off. She practically chased me down & then went right through my handbag....rude!!! I didn't think I looked dodgy, haha!!
