In SF the chains have terrible quality, but in other places you can actually get pretty good pizza from a chain, if the style you want is in their lineup.

Where I moved from the chain pizza was all pretty good. One day after I moved here I needed something quick and familiar so I ordered the same thing I used to get, and it was awful.

So it comes down to the local management, and in areas where management is sound, the pizza is fine and robots add no value in time or quality.
