I was talking with an employee at a grocery store, who told me that management one day decided to review the surveillance footage, and fired a bunch of employees who were caught pilfering.
Someone got fired that day.
Case in point - one time the cash machine on the bank exterior disbursed an extra 20 to me. I counted it carefully, sure enough, an extra one. So I went around to the other side, went in, and handed it to the teller with an explanation. She about fell over in shock.
It's kinda sad, actually.
