Bees like caffeine too

Just like people like caffeine in our drinks, bees seem to like caffeine in their nectar too and go back to flowers whose nectar has more caffeine. I didn't know this, but caffeine occurs naturally in plants as a poison to predators that eat them, but caffeine in smaller doses that is present in nectar seems to attract pollinators. So my question is: Are we built so that caffeine is good for us, or are we just addicted - or is a little bit of both?
