That is a really huge chunk, but so are the returns, the RTW clothes left in the girls' area and the occasional shirt or underwear someone left on the crockpots that HL found. And there have been days when I'm putting away reshop that I get back to my cart with more clothes than I carried into an area because three guests decided to leave 10 Mossomo shirts, 3 clearance items, 4 folded shirts and a bunch of bathing suits on the Knox Rose racks.
The one that still leaves me scratching my head is pulling out the reshop that GS put in our basket and finding HL or Spot's Playground items. Some things are pretty obscure and understandable, but most of it is obviously not ours unless there's someone new up front. If it's got a red area with a price on it, I don't care if it's a pair of socks or a hat, it's obviously not ours.
