Automation is coming to manual jobs, and many low wage workers will be replaced. But they won’t be replaced by humanoid robots that will do the same job, that won’t be economically feasible for a while. They will be replaced by specialized machines that are cost-optimized to the job. For example, consider a pizza place. At some point, manually making pizza from scratch will be too expensive compared to buying a pizza making machine. But pizza making machines will be engineered to make specific kinds of pizza, with specific types of ingredients, and assemble them in on the dough before shoving it into the oven. Any new type of ingredient will require redesign of the pizza machines and pizza machine making lines, so it will be prohibitively expensive.
At this point, why make pizza in the pizza place and not at the pizza factory, freeze, and deliver to the restaurant where they can be baked and sold? And if so, why go to a restaurant when you can buy exactly the same pizza at a supermarket? Or even better, online, delivered to you?
The only reason to go out would be to socialize. Which means that ambience will be the main competitive advantage. A real human, hand-making your pizza from scratch, sounds like great addition to the ambience, but it will be very, very expensive.
