It's not just about serial returners. In the event the store is audited, the auditors will spot check returns, and actually call customers who have made them to verify they were legitimate. This is to protect the store against employee theft/returns.
Then it's an internal matter for the store to resolve. I have no part in that policy and how they deal with it is their problem. My personal information will not be part of their solution. When checking out and they ask, I just smile and say "no". If they insist or push the matter, I simply walk away.
The store-customer relationship
boils down to this: They offer a product at a posted price. I have a choice to buy at that price, or not. I may take the product after providing the agreed-upon money. End of story and that's the extent of the required relationship
. I do not owe them my personal information that they may conduct marketing activities such as sending me unwanted mailings or email.
Some may disagree, but I always provide bogus information to associate with "loyalty" cards, such as "123 Main St" and "(xxx) 555-1212". (There is no Main Street in my zip code) To me, the loyalty comes from them offering cents-off enticements and me purchasing there, thus allowing them to make a profit on my purchases.
You would be shocked and amazed at the complete picture that can be put together by data mining which ties together all of the 'breadcrumbs' that we spread around, and store loyalty programs feed into that. I don't want my insurance company calliing to say "Pat, you've been buying too much red meat lately and that's not healthy so we have to raise your rates" because they can access my shopping history. Carfax is an excellent example of this. Anyone can access records of what maintenance has been completed on my vehciles becase Carfax, Inc. has made agreements with numerous service facilities to gather and identify what wortk has been done on what vehicle identified by VIN. Is it really anybody's business how I maintain my car? Some might say yes, I say no, but Carfax is making a buttload of money doing it. And that's just one we know about.
Anytime my bank, credit card companies. mortgage, etc. send me their privacy policies, I *always* opt out of information sharing to the greatest extent possible.
