We do have lots of places like Sheetz that serve a similar function, but to be entirely automated is rare.

Automats might be a closer analog.

Vending machines work better when there’s more foot traffic and more density.

Vending machines with specialty goods (as pictured) need to be restocked every day and they require even more foot traffic. I think this is the biggest factor why OP’s vending machine is not viable in a lot of places in the US.

Multiple people already gave the correct answer. I did not tell him to shut up. I gave OP the tools to solve the problem himself in the future.

What are you upset about?
