It doesn't take a lot to impress Mitt Romney.

At a campaign stop in Pennsylvania on Sunday, the presumptive Republican presidential nominee told a crowd that he had been astonished by a touch screen computer used to order food at the Wawa gas station chain.

"Where do you get your hoagies here?" Romney asked a crowd of supporters at the Cornwall Iron Furnace foundry. "Do you get them at Wawas?"

"No? You get them at Sheetz?" he wondered after several people shouted, "No!"

"Well, I went to a place today call Wawas, the candidate continued. "Some people don't like -- I know it's a very big state divide."

But it was the system of ordering sandwiches using a touch-screen computer that "amazed" Romney.

"I was at Wawas," Romney explained. "I went in to order a sandwich. You press a little touchtone keypad, alright? You just touch that and, you know, the sandwich comes up. You touch this, touch this, touch this, go pay the cashier. There's your sandwich. It's amazing!"

During President George H.W. Bush's failed 1992 re-election bid, he was criticized for reportedly being amazed after seeing a supermarket scanner. Unlike the Romney's bewilderment on Sunday, Snopes determined in 2007 that the Bush scanner story was actually false.

Wawa first implemented the touch-screen ordering system in 2002.
