I'm doing that more and more. I wish some chains like Food City, Ingles, and Krogers, would drop the blasted discount cards though. That too is a huge invasion of privacy and actually back door carding. That is if someone is naive enough to put their real name and address on the form to get the card. As for me I'm known as shoppers Elmer J Fudd, Gomez Addams, & Herman Munster. :>} No ones questioned it yet.
And they won’t. I go to FC from time to time and they have a card attached to the keyboard. Just tell em’ to swipe it. Same with the others also. I use local hardware stores and local vice stores. I seldom show an ID. :^)
