I worked on the other side of retail, so I'm getting a big kick out of this.
If we're going to lock up Timmy for fast-tracking his treasure hunt, then let's lock up Grandma for removing the bedding item from its plastic so she can "see it" (properly displayed on the store floor), Jhonny who needs to "confirm" the widget is the right size (the exact size was displayed on the now ripped up box), or short foot Freddy who grabs the pair 9's but switches one out for an 8.5 (this is such a gray area).
In all the cases above, it was impossible to get those items back in the box properly, and they would always wind up being clearanced. We simply called this "The Cost of Doing Business" in retail and it seemed like the vendor and customer always won.
