RE House of Waffles mentioned above- you walk into a casual place and you subscribe your PAN. A AR hostess indicates which table is open, although there may still be someone working the door for someone who comes in with a bare bones comelink and no AR gear. You review the menu either in AR or on your 'link. If you know what you want you just order right there. If you want to talk to someone you probably hit the "call server" button and a server will turn up.
In the kitchen there are fairly advanced versions of the home autocook cranking out the food, but there are probably several employees who are reloading them with raw materials, keeping the plates on the bar organized for pickup, making sure that the toast from machine A gets to the eggs on the plate from machine B. Probably no one is back there that we would call a cook, but there would be some hands on logistics to make sure it all went well and stayed organized.
Servers still bring you the food, check to see if you need a soycaf refill, etc. The cost of the meal was debited automatically from your account when you ordered it, so there is no cashier. If you want to leave a tip you switch to AR and drag some funds to the server's AR icon and wait for the "ching" noise.
There would be a manager or two that does the paperwork, schedules everyone, orders supplies, and calls the repair service when the dish washer goes on the fritz. Pretty much everyone but the manager would be flat low lifestyle. The manager probably doesn't make a full medium lifestyle, but is a bit better off.
