I think the McDonalds of the future may look more like a vending machine than a restaurant. Of the the things you listed, only "test a burger patty for the correct internal temperature" is actually related to producing McDonalds food, and that is certainly automatable.
But that aside, if all that's left is basic cleaning then McDonalds could simply contract a cleaning service. I'd guess that a single team could service at least 10 fast food restaurants a day. And then how many years before running the cleaning service only requires one person?
