A Massachusetts carpenter took a client to buy some lumber at Home Depot. When Michael Panorelli needed to do some quick math his client grabbed a pencil next to the cash register. That's where the trouble started. The absent-minded carpenter pocketed the pencil, and by the time he reached the parking lot, an employee gave him a letter saying he was banned from Home Depot worldwide because of shoplifting. The company has since apologized for the overreaction.
