One very large difference is that even at the height of the supply problem (store stock levels are pretty much back to normal now), suppliers weren't out of food or unable to restock the stores. There was plenty of food being supplied to the stores, but people were arriving very early in the morning and buying up as much as possible. Once limits were imposed, this started coming under control.
