Rob is blowing a whistle, over and over.
Bob: “Why are you blowing that whistle, Rob?”
Rob: “To keep the dragons away.”
Bob: “I see no dragons.”
Rob: “It works!”

In my area (San Francisco Bay Area) it depends on how much pedestrian traffic is expected. I live in the suburbs and, as I said, the walking light only goes on if the button is pressed. But if I go to San Francisco itself, lights are all on a timer (and there are no buttons at all).
