Also, you have to keep in mind the relative size of the players. If the grocery store is small, and Unilever, for example, is responsible for 10% of the inventory, but they're not happy with what the store is doing, it's probably really easy for them to say "Our delivery trucks only come every other week now, because you're not profitable enough.
