Modus operandi: The waitress whisks away your credit card and swipes it through the restaurant's register. Then, she pulls out a small device, about the size of an ice cube, from her apron and swipes it through that, says Sergeant David Schultz of the Fort Bend County Sheriff's Office in Texas. While you're scraping the last of the chocolate frosting from your plate, your credit card information has been stored in the device, known as a skimmer. The waitress returns your card and performs the same magic trick on dozens of credit cards in a week.
Known whereabouts: The data-stealing waitress has been known to moonlight as a bartender, sales clerk or at any place where she can take your credit card out of sight.
