I was a bit of an amateur mixologist as a child, and the top machine was my pallet.
But what was more, the corner store gas station that was down the street from my childhood home had multiple machines, each with 4 or 5 different drink options.
Years later, a friend of mine worked there as a summer job and told the friend group to avoid the fountain drinks so we did, and probably all still do.




Eh, massive correlation is still not causation. No matter how massive.
