I just received a phone call—at my desk—from a number I didn’t recognize: 800-995-4532. I don’t usually receive calls at work, so I’ve gotten into the habit of Googling them before picking up. (Almost every single time I don’t follow this procedure, I wind up talking to a Disney comics fan who wants me to look at his portfolio.)

So I Googled the number, and it turns out it’s Payless ShoeSource wanting to tell me about a “buy one, get one free” sale they’re running. And yes, I know that’s not what they’re calling it, but I absolutely refuse to call this a “BOGO.” “Buy one, get one” means exactly that: you get the one item you bought. “Buy one, get one free,” on the other hand, means you get two items when you only paid for one. (Interesting tidbit: “shoplifting” can mean the same thing, but the stores don’t typically encourage such behavior. It’s true!)

Ahem. So why did Payless call me at work (at 2:30pm, when I’m not likely to drop everything and run out to buy two pairs of shoes)? A few weeks ago, I bought a pair of boots from Payless. Where I was asked for my phone number at the cash register. I’m too nice to flat-out refuse, so I gave ‘em the number at my desk.

Here’s what really irks me about all of this: when asked for my phone number, I was never told that I would receive phone calls regarding future sales. If anything, I was given the impression that my phone number was needed because I was paying with a debit card, or to track demographics (like when other stores will ask for your 3-digit area code). I was tricked into being barraged by advertisements, just because I don’t want to be a jerk to a store clerk who’s simply doing as she was trained. I was never asked permission for this use of my phone number, and never offered it. This use was forced upon me by somebody who cares nothing for me as a person, but merely for what he can get by using me.

You could say Payless raped my phone number.

Now I like the boots I bought. I was ready to make Payless my “the shoe store” for the foreseeable future. But as happy as I was, I feel like I’d be encouraging this sort of customer disservice if I continued to buy from them. Which sucks, because I don’t want to have to find another place to buy shoes.

“Real permission is different from presumed or legalistic permission. Just because you somehow get my email address doesn’t mean you have permission. Just because I don’t complain doesn’t mean you have permission. Just because it’s in the fine print of your privacy policy doesn’t mean it’s permission either.” — Seth Godin, Permission Marketing

I won’t forget this. Payless has lost any and all trust I had in them. They may never earn it back. And all because they refused to consider others as more important than themselves.
