It's your dime.

This is what the Pontiac guys had. If you did it just right you could slide the bottles right out. No nickel. I'm pretty sure they new I was doing it. LOLView attachment 1715452448
They had one at the garage near where I lived and was outside. After the garage was closed we would flip the lid off and drink with a straw. One day he changed the machine so now more free drinks.
