Everyone Shows ID for Beer in Tenn.

"Richard Rollins, who owns a convenience store in Nashville, is already using a computerized scanner to check everyone's driver's licenses when they buy beer. "We just say we're trying to keep our beer permit, and this is the safest way," Rollins said."

"I don't mind them asking for my ID, but they don't need my driver's license number," said Campbell, 43. "I'm just buying a six-pack. All they need to know is how old I am."
