It has occurred to others.
The owner of the "Takin' Care of Business" cleaning service reportedly did first-class work on his job at Richmond International Airport in Virginia. As it turns out, he was cleaning up in more ways than one. The man managed to steal several thousand dollars from a United Airlines drop safe with a little help from....his vacuum cleaner. Richmond police say the man used the vacuum's hose to suck up cash, checks, and credit card receipts from the narrow drop slot of the safe during his nightly rounds. When the deposits began disappearing, bewildered airport authorities set up a surveillance camera near the safe, and managed to videotape the cleaning man in the act of "takin' care of business."---From Dumb Crook News.
