It’s not a fixed percentage but it’s close enough to think of it that way. The real problem is that they are legally prohibited from using tip share to pay their back of house more. This puts them in a situation where if they want to raise kitchen staff wages they have to raise prices and restaurant customers are extremely price sensitive. Several high end restaurants (were presumably there would be less price sensitivity) have tried doing away with tips and raising their prices to pay all staff a more uniform wage. It’s largely failed. Customers don’t like higher prices and front if house staff largely prefer tips as they make more (at the cost of lower pay for their kitchen colleagues).
