That's horrible. I used to work in a restaurant too during college... the break room didn't have lockers, but had coat hooks where we would all hang our coats & purses. One of the ham waitresses was going into other waitresses' purses, taking out their credit cards, and either returning them a few days later, or writing down all the information and returning them immediately. A few of the waitresses were getting suspicious charges on their cards, and an investigation was launched (not sure if by the credit card company or the police or who). Anyway, the ham was caught, fired, and charged. Serves her right.
