You were certainly right to not reach out to take the bottle- he might have grabbed your arm! I rode with a woman friend the other day who said years ago she was stopped at a red light next to a pickup and the guy reached out the window and grabbed at her and she took off and managed to get away. Now she never stops right next to a vehicle window.

I am more of a worrier than you. I would have turned right around and hightailed it home as fast as I could as soon as I saw that truck waiting on the side of the lonely road ahead of me.
