[Got the Bug]

Fry's Electronics and Costco are the only two stores that I shop at that check your receipt at the door. If the line at Fry's is backed up at all, I just walk by.

Costco is a different story. It's part of the terms of service that you agree to as a "member" of Costco club. I read a story where someone disputed the requirement at Costco and they just canceled the persons membership. I go to Costco once a quarter, so it's no big deal.

Any other store, I'm walking by any security check at the door.
