Ultimate Electronics.

I went to Ultimate Electronics the other day. They're nuts, just
like Radio Shack. The ask for your name/address/phone number
when you buy something...

They have televisions there that cost $15,000. What kind of idiot
would spend that much for a TV? That's way too much...

The TV looks rad, yeah. It's High Definition and only a few inches
thick. But $15,000? I think not.

For such purposes, my address is:

Buckingham Palace
The Mall
LONDON W1

I think its for data purposes, but do you have to tell them if you buy something? What if you dont want to tell them?

I dont know if you recall a Seinfeld episode, kramer mentions "Why does radio shack as you for your phone number when you buy batteries?
