I wish someone would stock the shelves at my local supermarket. They must have a different crew pulling stock from the back room than stocks the shelves, so they clog all the aisles with pallets of stock starting around 8pm and no one within a mile of it actually putting any of it on the shelf. Customers will cut their own product out and if it happens to be at the bottom of the pallet they'll just scatter everything to get to it. Maybe a few hours later the stocker will deal with the mess and actually shelve it.
I see that once in a while too, in the evenings. I think you’re right, that someone thought it would be more efficient if the day crew positions the pallets so that the evening crew can stock shelves without having to move the pallets out of the back. Might be a good idea at that, IF the evening stockers get right to it. Otherwise, a mess such as you describe.
