Debating applying for a Night Stocker job... <.< I might be crazy.
I've done that. There's something oddly peaceful in working the graveyard shift, and no one really bothers you so you can work at your own pace... to a point, anyway. Also a lot of opening boxes (it's like Christmas!) and at the end (assuming this is a grocery store) you got to do a thing called "facing" the product. In other words, bringing a couple of the product to the front of the shelf so that it looks fuller than it is, especially if you just shove the stuff in there (guilty). It was fun, but it took a lot out of me, and there's plenty of lifting to do.
