Here they replaced all the markets that were staffed by people with these big vending machines that are 3 or 4 refrigerated cabinets (even chips are refrigerated). You pay, wait a bit for it to process it, and then it unlocks the doors and you grab whatever. And if it gets it wrong there’s no dispute process to tell it you didn’t pick something up (I think there is an email listed but I didn’t care enough the time it messed up to send an email). And half the time when you click the pay button to finish, it’ll complain about a door not locking.
