I know you can opt-out of the telemarketing and UBE attacks on your life. My question is: How do I opt-out of the sales pitch and invasion of privacy at the check-out counter. Yep, that's right folks. A certain large computer hardware/software chain now wants to know your zip code when you check out (I was paying cash for a stack of CDR's). They also wanted to know if I was happy with my current service provider.
