It’s just a vending machine what makes this a dystopia?
So this isn’t so much a vending machine replacement as it is a coffee kiosk replacement. One that would normally have a human employee or two and is now manned by a robot. The customer will likely end up paying more for their coffee due to the gimmick of the robot. And you know the payment screen is still going to ask for a tip even though the robot doesn’t need it.
You’d think the tip would go to the person who comes in at night to clean and restock, but he/she/xe’s likely paid even less than the baristas.
