I remember as a kid walking around the city checking every pay phone to see if there was any change in the coin return. I usually could find a few bucks a day, enough to get a good candy allotment for the day.
Used to do that. Get a couple quarters to play pacman. Also could do the paperclip trick.
I did that when I was a kid. I probably found change in a phone nearly as often as I didn’t. Usually only a few smaller shinies jingled into the bottom, but it always felt like you just won something.
