When a restaurant owner suspects employees of not doing their jobs — whether it be stealing, lying, mistreating customers or generally doing lousy work — they call in the Mystery Diners. These Mystery Diners are undercover operatives who go into restaurants, bars and food-service establishments with hidden cameras to perform surveillance to find out what's really going on when the boss isn't around.
