I was at Wal-Mart 12 years. You wouldn't believe the stuff people try. I've seen oversize women with tons of meat hanging by various means under their clothing. The funniest(?) I saw was a man who returned his chain saw in original box with receipt. The fairly new associate took it and gave the.refund. Opening it later, they found a log in the.box. What I don't understand is why employees suspected you BEFORE you reached the checkout-unusual. Usually this occurs when someone realizes they're being watched and ditch the item on the way to checkout.
