Internet personal data & big business -how do they get my info?

Kitty and I went to Burger King in Milledgeville just the other day. I paid with my bank card. Out pops my receipt with "ROBERT" printed on the top for my number order. That's a little "too big brother" for me. But what do you do? Nuthin.

In person I always pay cash.... always. No name on my receipt. And nobody really knows where I shop in person. :)
