Maybe he wanted to leave because you were acting all weird and angry?
Could be worse. They could be Amish.
Quite the contrary, after my initial low-key contact, I didn't say a thing to him. Meanwhile he was walking in another aisle parallel to me in the parking lot apologetically blabbering the whole time. The only thing I really did after my initial comment was to hold my cell phone up to get the second photo of him and his car.
BTW, next time I see suspicious vote registration activity, I will first go home and return with my GoPro camera to record it on good quality video.
