Shades of the future that never was! A restaurant in Nuremberg has done away with waiters (in a completely humane way) by replacing them with a gravity-feed system and networked computers at every table.
The kitchen’s above the dining room. Customers order using touch-screen computers at their tables, and when their food’s ready it slides down gently on spiral rails.
I suppose that to complete the circuit you’d want more rails leading to dishwashers in the basement, but for now it looks like the jobs of buspersons are secure. More here.
This is somehow like the automated parking garage that was designed in Germany a couple of years back. A trend in vertically oriented job reductions?
