The Progs & Co. have been playing a game of chicken with economic reality, imposing this silliness in cities like SF, Oakland, and Seattle. The Land of LA is the 2nd or 3rd largest city in the US, IIRC. Besides being an entry-level-job-killer generally, it is likely to be the critical mass of stupidity that will bring automation into fast food stores, with machines doing the food prep currently being done by people. Such machines do exist and evidently are reasonably available. Whether the buying public will accept machine-prepped food will be an interesting question.
I doubt the DU folk would mourn the demise of M or BK or ... The teens who had hoped to have those entry-level jobs might feel a bit differently.
