Hey now, let's not get carried away, these jackass restaurant owners want to make it clear, the "Living Wage" guilt trip is the tip part, and the fees THEY put on are to pay for "benefits like healthcare" and you're not allowed to consider it part of the tip.
Nevermind that California doesn't even have a lower "tipped" min wage like some states do, so by supporting tipping, we're just saying that servers simply "deserve" more money for some reason than people who stock shelves or pick orders at Amazon or Walmart.
If it is hard to find staff the wages go up. At least that's how it works in my country.
Although I will admit service is notoriously bad over here but in honesty that's secretly how we all want it.
