When I worked at a grocery store, Sunday premiums ($1/hr more) were eliminated. The claim was that theft was too rampant when a month before, the manager congratulated everyone for keeping losses down. To couple that, the next week, he went on a trip to Africa for a month to hunt animals. The result of this was that theft actually started to happen. Employees would "accidentally" bust open a six pack of beer, bring it to the back (no security cameras) and poured it into cups of pop. Personally, I had Lobster Bisque every Sunday for a month.
