Worst/Weirdest/Dumbest Piece of Unsolicited Inoffensive Advice You've Been Given?

[Skywatcher]

Just remembered this incident while watching a repeat of Friday’s “On Patrol: Live”:

@Skywatcher

Many years ago, I was in a crosswalk at an intersection controlled by a flashing light. Traffic had been clear when I started across but I was almost on the double-yellow when Mr. Dumbass came from my right and stopped in the crosswalk to lecture me on his version of proper crossing etiquette.

Another pedestrian on the opposite side witnessed the driver’s odd behavior. “What was that all about? This is a crosswalk!”

Says I: “You know that and I know that…”

I see that crosswalk and its signals have since been removed.
