A good server is an emissary from the kitchen, who knows the menu, and helps you find the best dishes. A great server establishes rapport with the regulars, anticipates their needs, makes them feel welcome and comfortable.

Unfortunately "server" is not considered a respectable career but something you put up with before your film career takes off, or how you pay your college tuition for that juicy psychiatric nurse degree.

So nobody can be paid enough, or retained long enough, to care about customers or the food. So 25 years from now, the best server will be a Roomba with a prominent QR on its back.
