Well, he apologized for the "babydoll" immediately, so it probably just slipped out and he understands respect and boundaries.
I'm guessing he may have left the tools, too, because he wasn't sure how to lead up to something.
I recently had a cable guy hit on me and it was sweet. I say have your fun when it presents itself!
But, I would NOT invite him for coffee or anything. I would just call him, tell him about his tools, and see what HE says when...
