When the dishwasher that Greg bought at Lowe's broke down after a failed repair, he called up the store. A manager instructed him to bring the appliance, which was covered under an extended warranty, in to the store and they would exchange it for one that actually worked. Only when he brought it in, the employees on duty treated him "like a criminal" because he had lost the receipt in a recent move. Wait, don't appliances have serial numbers that they can use to look up warranty information? Nope.
