Indeed. Another scam, practiced at Wal-Mart and probably other stores, is to pick up a receipt from the floor or parking lot, select the same item as on the receipt, and present it for a refund. Wal-Mart emps are instructed to tear up any they find. The more enlightened store managers have the emp write their name on the back of the receipt, which is put in a jar. Once a month one receipt is pulled out and that emp gets a $5 or $10 slip to spend in the store.
That’s a pretty good idea.
