They definitely have it in other California cities too. And not just in restaurants.
A chain resale/consignment hipster shop in NorCal started adding a percentage service charge years ago with the same excuse, and you’d only find out about it if you looked at your receipt. The fucked up part is that they also raised their prices so high that I couldn’t shop there anymore. It’s one of those buy/sell/trade clothing stores, so the whole point was to pay less for decent clothes. But if they’re already raising prices significantly, why the fuck do they need yet another charge to pay their workers.
I also think they really must believe it makes them seem “progressive” somehow. Like “oh look, we’re on the workers’ side!” and they hope no one eating/shopping there will think about it any more deeply than that.
Especially fucking Wiley. If you’re a student paying hundreds for a textbook with a “supplemental code” that makes it so you can’t buy it used, then it’s probably by fucking Wiley. Fucking greedy cunts.
