Quite a lot of the time, numbers aren't snagged online, but at restaurants, where we willingly hand our card over to a person who then disappears from view....
Or even at those restaurants where they still insist on putting the whole CC number on the printout, which we then, if we're not paying attention, leave on the table as we leave. WHO knows who might take a peek and get our name, CC number, and CC exp?????
