There are a few different things touched on in your comment, and I'll try to respond to them all, sorry if I miss any.

1. Losing jobs with no demand is not a bad thing. If you list a job, and nobody will take it for a year, then the market doesn't want that job. There is an tendency to obsess over the number of jobs as a marker of economic health, but it's a correlation at best.

2. The restaurant industry specifically is hugely over saturated, plenty of restaurants succeed paying a living wage, if you can't then you need to make adjustments (e.g. change menu, move to a different location, etc).

3. A restaurant which can't turn a profit is a hobby, not a business.

I imagine that at some point a UBI will be necessary, due to the lack of jobs lost to automation, but the purpose of UBI should never be to support the exploitation of workers. In fact it's thought processes like that which make people argue against implementing UBI "Well if my landlord knows I get 1000 a month from UBI he will just charge me 1000 more for rent" or "If my boss knows I get 1000 a month from UBI then he'll drop my salary by 1000 a month".
