I worked as a barman. A skilled barman can pour two pints simultaneously and take a new order from the next customer, but I believe with machine assistance this could be greatly increased. I could easily imagine replacing a staff of say 5, with 1 or 2 workers. Large order for 10 pints, 3 cocktails and 7 shots? A staff member presses a button, and the correctly sized, just cleaned glass pop out of a slot coming from the automated dishwasher, and the pints and other drinks are poured to perfection, every time. The barman checks the order is correct, accepts payment, gives change if its in cash, cleans the tables and changes the barrels when it's quiet. You could get a hell of a lot more work done with a small number of low paid staff and machines that can pour endless drinks at once. So while you don't eliminate all the staff, you can drastically reduce the headcount and greatly increase productivity, at least in theory.
