My favorite one was thrown out at me from a car window.
No choice but to go to the grochery store on a day when my walking wasn't too great. I always look both ways before crossing the walk, especially on days like that. No cars when I started to slowly go across, but a guy comes barrelling down from the entrance and screeches on the brakes when he gets close.
"Can't you go any faster?" he yells at me.
My response was to shake my head and say, "Nope. And by the way, the speed limit is only 15 through here."
He kept mumbling, but he was blushing too.
