Well done that man.
Similar thing happened, I was driving near my village, quiet road....a. .....ole threw remains of a pie out of car window. I stopped, picked it up and followed him, stopped alongside him at traffic lights, beckoned to him, he opened his window, beautiful shot with remains of pie.
He chased after me, I stopped at a shop in the village he got out all 2 foot nowt of him, but changed his mind, I'm 6ft 2, and I wasn't covered in pie.
