There's a big difference between McDonald's and a high end restaurant, even if you just order a hamburger. McDonald's has already been working on automation. Have you noticed that humans no longer dispense drinks there? They are also working on getting rid of the human order takers.
Agreed. There will probably always be specialty and high end restaurants, where it's more about the experience (in some way). If you want mass produced, a robot is great for that. But they're not so great for limited runs. Which is to say that general purpose robots (for any application) are a long way off.
I think we'll adapt as a race, but it'll be mighty uncomfortable for some (say those reliant on low skilled jobs, truck drivers, fast food workers, etc.). It's not to say that the way things will get done will even look the same as the transition occurs. I suspect many things will look different. For instance, rather than speaking your order to a person at McDonald's, you make your selections from a menu and a machine creates it, and then you pick it up and take it back to your table. Redbox already does this for movie rental. Think about how they've changed what we expect of renting movies... Same for home construction, particularly of the cookie cutter variety. Rather than a crew of people going through the motions to excavate a hole, lay a foundation, frame the house, put up drywall, paint, etc., Maybe it'll just be 3D printed with a huge machine (this tech actually exists, if in its infancy). Or maybe we'll switch to brick houses because they make brick laying robots (not humanoid, more like boxes which can move around). The next decade or two will be interesting!
These menu displays are wonderful toys when you get to use them (they're in every McDonald's in my city). Looking through all the menus makes you realize how many things you could do before to customize your order. I usually add extra patties to my burgers, add extra onions/lettuce, and then go to the "free condiments" section and order 5-10 peanut packages. All of which are happily placed on my tray without question, which is the only time I should interact with their employees: when I'm receiving my food.

For restaurants where one of the main draws is price I think automation is inevitable as a cost saving measure.
