That’s where we’re heading. Was in a nice bar, not in US, recently where a robot by the front door took your table request. A human did come out to take us to a table but that wouldn’t be necessary. Though there were human bartenders, no waiters, replaced by robots. Table clearing, a human loading robots with multiple shelves which returned to the kitchen. If you walk in front of one they go around you or halt if there isn’t enough room. I assume someone loads the dirty dishes in a dishwasher and takes them out but didn’t see it so who knows. Bartenders were human.
