I still remember buying "pop" out of those old cooler style soda machines that the soda was sitting in water. I'll never forget the tinkling sound they made when running. You had to slide the bottles down a track to the point where there was a gate device that would release when a coin was put in and you could pull your bottle out. Oh the frustration if you hesitated a little and the gate would re-lock without you getting your soda. Royal Crown, Orange Crush. Grape Nehi, Dr Pepper and of course Coke or Pepsi.
