Bees and flowers have a commensel relationship where the flowers provide nectar and some pollen to the bees in exchange for distribution of the flower's pollen for fertilization. The bees aren't "stealing" anything. That nectar has no purpose to the plant if it doesn't attract pollinators. Of course neither the bees nor the flowers are conscious of this relationship or their roles in it as it evolved naturally from the natures of both plants and insects.
