Is there anything better than a vending machine? Except when they're out of Hot Cheetos, of course. Or when the candy gets caught on on the hook instead of falling. Or when your Mountain Dew gets lodged in the dispenser, making the whole thing as useful as a money-eating box. Or when you get your arms stuck inside two different vending machines.
None of those are problems you'd have with the very first vending machine in the world — though your options would be a bit limited.
