When I was a kid they had soft drink coolers like the one here that had circulating ice-cold water in them. I don’t know the temperature of the water, but I am guessing it was slightly over 32-degrees.
Anyway, you would move your drink to this little rectangle area, put in your coin(s) and pull the drink out.
Sooooooooooooooo cold. Sooooooooooooooo good.
