Haha, we got that offer and had a good laugh over the shredder.
I used to work at a high end retailer, where there was enormous pressure (and reward) to develop personal clientele. You bet your ass we took note of what kind of card people carried. Dude, you use a black AMEX (or whatever)? I am only showing you the very best stuff and I'm showing you shitloads of it, because this card tells me little about your net worth, but it tells me everything about your willingness to BUY, and that you can be influenced by the notion of prestige. Oh, hell yes, I want you as my personal customer! Forget about a target on your back, yours is zeroed in right on your wallet.
