Advertisements I, just like every consumer, choose what and when to give information. And yes, I do have the right to tell them to stick that (and by that I mean walk out the door). By shopping there I am looking for something that has value to me. This does not give them the right to require this information for a cash purchase. How exactly where they protecting their business with the OP? I do not purchase or even think about purchasing from Radio Shack for this very reason. You know, I don't think your tone was really needed. Again by 'Stick It', I mean tell them politely that you are not going to comply and shop elsewhere. And of course, call and complain to their corporate consumer relations department, so that know of the problem and you're not going to shop there because of it.
