How much is lost?

The proliferation of reusable grocery bags has me thinking, and it also has me asking this question: since a lot of them are just hanging in the store, ready for you to pick them up if you decide to buy one, how many have been stolen since they became so widespread? How many people have picked up a bag, taken it somewhere in the store, torn off the tag, used it to shop, and then never paid for it. Now, you can say, well, they aren't that expensive, but come on, a dollar's a dollar, and if someone stole a dollar from me, well, I wouldn't be too happy. As far as I know, the bags don't have anti-theft devices embedded in them, so who's to say that a lot of them aren't going missing? I mean, I want to think the best of people. Really, I do, but well, I've seen a lot of people do a lot of things that they shouldn't have, and while they might be remorseful when they're caught, I find it harder to think that they'd be remorseful if they hadn't been. What's next? Are they going to have the store cops in charge of preventing shoplifters focus on the bags, or even hire people for the express purpose of monitoring the bags? That's going to get expensive really fast, don't you think? I don't know. Maybe I'm putting too much thought into it. Maybe I'm being pessimistic. Maybe I've been working in retail for too long. Anyway, it's just a thought I had, and considering that the issue never seems to get mentioned, I was wondering if anyone had ever thought about it at all.
