I work at a Target store and we've had a few people get fired for some pretty stupid things. About a year ago, a kid working in the electronics department thought he could get away with stealing a camera. His plan was to buy the camera, process the return himself, and still keep the camera, hoping nobody would notice. Well, BUSTED! He was fired on the spot and arrested.
The best one was our store manager was fired for sexual harassment. He was in his early 50s, and would walk around quietly and stare at the young girls working at the store for hours. Once rumor got around that he was doing this, Target Corporate undercover people came in, watched him and a few days later, told him to pack his bags. When asked why he left, other managers in the store told us that he left due to "difference of opinion." Gotta love the grapevine.
