One of my favorite stories like that was when I pulled up next to a couple of "Elder Missionaries", white shirts and ties and all, at a light. I was out from the right turn lane, as I always am when going straight. These young guys were at the curb pushing the walk button like crazy. I casually mentioned that since there were cars in the intersection too, pushing the button did not affect the timing of the signal, and they were blocking cars turning right.
This one kid gave me (a fifty something Clyde) a contemptuous look, and then exchanged a smug look with his partner. The light changed, and the both stood on it. So did I. The difference was that they were in top gear, I was in third.
I got across the intersection, looked back and they were only a quarter of the way across. When I looked back again, a mile later before making my turn, one was about a quarter mile back. The other had apparently given up.
