I saw an interesting situation. I was in a store with some empty shelves and a lot of half-empty shelves, and at the end of each aisle there was a big stack of boxes wrapped in plastic. They had new inventory, but it was packed up. My guess is that so many people are out sick that they don't have the staffing to run the store stock and the shelves during business hours. I went back today. The shelves are less empty, and the big piles are gone, but they have stuff stacked up, in an orderly way, so you can grab what you want, at the ends of the aisles at the back of the store. Most aisles have no end caps and there's usually nothing at those ends. I don't know if they have too much of some stuff or if they just decided to stack it at the end because it's quicker than putting it on the shelves.
