Repairing These Vending Machines

I remember having a coffee vending machine in college. And the coffee didn't taste all that bad, either.

I just did not know how complicated these machines look from the inside. Having to repair these must be hard too.

I don't know the intricacies of how these machines work, but the idea of it mixing ingredients of different substances at different temperatures for you at a press of a button blows my mind.

It clearly is a leap from just dropping candy or chips.
