It Takes A Thief
When the owner of a new car wash in Fredericksburg, VA found the till was coming up several hundred dollars a week short, he accused the manufacturer of the system of having duplicate keys, and of ripping him off. The loss came to thousands of dollars. In response, a video camera was installed, which caught this group of starlings ripping off quarters via the coin-return slot. This story started going around the 'net again recently, although it is actually several years old.
