I worked in the restaurant industry from the age of 12 for over 20 years across all levels of quality. McD's, hot dog vendor at the student grill, mid-range, and ultimately fine dining.
In NYC during the 90s we were paid 2.01/hr because the industry lobbied crying poor house because we earned so much money in tips. In '94 the IRS came in and checked credit card receipts and concluded that we should pay 18% tax on all tips, which cut our shady take home tips down a hefty notch. I owed nothing the year before and that year got slammed with a $4k tax bill, which was a lot for a kid in his 20's trying to pay off student loans.
Working in American restaurants can be a total nightmare. Customers bring all their baggage, entitlement, and unspoken insecurities and push it off onto waiters and cooks, all because they "have" to tip. I was constantly in jeopardy of having some rich bastard go off on me because the coffee wasn't hot enough or their food didn't come out on time during the rush. I grew enormous rhino skin which ultimately helped me later in life, but I lost a lot of blood in the war.
I'm not sure why CA is making this move against fast food chains, except maybe to put them out of business for health reasons, and try to make some impact on the cost of healthcare. But what they should do is what's happened a lot in NY fine dining, which is to end the practice of tipping and just pay living wages like they do in Europe, then bake that into the prices. It would bring a higher degree of professionalism and better quality and help solve the working poor issues.
Trying to live in CA on minimum wage is next to impossible, so the working poor will catch a nice break--automation does away with them completely.
As an aside dear mother insisted on taking me out for a steak dinner this week. We went to Ruth Chris during happy hour and got the discounted offerings. The bill came to $175 including tip. Service was great but the food was pretty crappy. I can do much better at home, as some others have said for a fraction of the price. But mom was happy to have the "experience."
