A robotic replacement of a Pizzeria is a sign of the times I suppose. Food service workers have been underpaid and overworked for the longest time. For a bit, wages crept up due to labor shortage but it also prompted automation. There is a sweet spot for cost vs quality of Human rendered service compared to automation. If this becomes the fate of pizzerias and more, it would mean the balance has titled in favor of robots. If the quality of the finished product is on-par with the human made equivalent, then for many it will make no difference that a robot made it. 

This is specially true if the quality of service provided by the human staff was nothing to write home about. The customers would trade the hassle-free interaction over the dubious benefits of humans processing their pizza order. I can think of a dozen establishments where the customer may have a better experience without disgruntled staff serving them. It is unfair to the workers in the the short run but one would hope this will prompt upskilling and the labor force moving in a direction that offers better compensation and benefits than working at a pizzeria did.
