They distribute pollen via mechanical side-effects (on their legs and bodies), but that is not their goal. That effect is the plant's goal, which is why it produces nectar - to lure them.
They distribute pollen to pay for the honey. The better they do it, the more flowers, the more honey. But in the end they are not going to complain individually if there is no pollen. They will of there is no honey.
It's the original Sharing Economy.
