The little round gaskets from the beer bottle and soft drink bottles... wow, they are days we will never get back. I remember the gas station I worked at as a kid had a long open the top coca cola machine and you would put in your 15 cents and I’m trying to remember but you took your product down the line that was to thin to lift a bottle out of so you couldn't steal it, but went through the maze of metal to the front of the machine and then lifted it out and it went through the mechanical vender unit. Then you would open your bottle on the side of the machine and there had to be hundreds or thousands in the corner of that gas station for the 5 or 6 years I worked there, I can’t remember anyone ever cleaning them up... Good Times.
