Be aware of people on cell phones near you when you are using your credit cards in any environment. Many of the camera phones contain pretty good digital cameras and getting a shot of your card is a snap. And with the inexpensive software out there it's easy to get your name, credit card number and expiration date and do what they want with the information.
