Today at Macy's, I was digging through a rack of clearance jeans when I noticed something weird. The jeans I was looking at were supposed to be Calvin Klein, size 6. But the little CK tag inside the waistband was peeling away. Usually they're stitched in. So I looked at the button on the jeans. Not Calvin Klein. The size tag was for a Junior size, and the jeans showed signs of wear.
I took them up to the manager and told her she needed to give them to Loss Prevention. Someone had cut the tag from a pair of CK jeans and glued it into the waistband of the non-CK brand jeans and then returned them to Macy's, probably using the receipt for the real pair of CK jeans they'd bought earlier.
Sadly, that happened a LOT. I worked there over the holiday season and the Loss Prevention office was full of stuff like that..clothes that had been doctored and swapped out with the real thing and returned, usually for cash. There are a lot of thieving SS people who do crap like that.
