I hate how when you are shopping at a store, other than the grocery store, and they ask for your phone number so they can punch it in to start ringing you up. I got some dishes for my birthday, and when I opened up the box one of the plates were broken. I took them back, and didn't have the reciept, they asked for the phone number of the person who purchased it and was able to bring up the transaction. Is this some type of tracking service? Stores will be able to see your spending habits. Enough of the information needed.
BTW, I got home with my new plates, opened up the box, and one of those was cracked. Geesh. I basically had to sign over my first child to take back the first box.
