Sad, but true - employee theft is a HUGE problem everywhere. My sis and BIL used to own a small deli in a professional building. Food, plastic utensils, napkins, cups & plates, even cleaning supplies routinely disappeared. One time my BIL stopped by at closing time and two employees were removing ten five gallon buckets of ice cream for a big party they were throwing that weekend.
They tried to act like, "how did that get in my car?!?"
