This will only work well when the company that provides this service has a product better than the Sirius Cybernetics Company's elevators. Those elevators had a built-in feature whereby they could read minds and see slightly into the future, so when a person got on the elevator, the elevator would read their minds and deliver them to the floor they were thinking about. None of this messy mucking about with fingertips and numbered buttons.

The McDonalds provider would have to read one whole weather cycle in advance in order to get the right mix of product into the "restaurant" during the night before the product is needed.




(Yes, Sirius Cybernetics was an invention of Douglas Adams, and was an important part of the general atmosphere of The Hitchhikers' Guide To The Galaxy almost forty years ago.)
