This has happened to me many times. Usually I don't care. If they want to follow me around while the real shoplifters get away with it, it's their loss. Literally. The only time I had a bad experience was on one of my first outings when a security guard clocked me the instant i walked in. I was totally creeped out and left quickly. I vowed to try to pass better the next time. I've been back there many times.
