It's what you don't know that allows you to sleep at night. According to this article in Time, something like 70 percent of all credit card skimming occurs in restaurants when the server takes your card away from the table and you can't see wtf he's doing. Turns out what some of these dirt bags are doing is copying your credit card data and selling it to other dirt bags that resell it or use it themselves.

But you can be sure that Bob dG going to be paying more attention to the behavior of servers from hereon.
