...I'm so happy that I write in untyped languages so I don't have to deal with any of this.

It's not a business of selling/repairing vending machines. It's operations of a single vending machine. Correct me if I'm wrong: the vending machine (soda, snacks) has long been automated, with no AI in sight. And the vending machine does not adjust prices. What matters is that (1) the vending machine sees some foot traffic, and (2) nobody sets it on fire. So what was the point of the exercise again?
