I think the point is that if a business wants its employees to make a living wage, they should pay them that wage, and make whatever adjustments are required on the business end to make that possible, instead of continuing to pay wait staff less than minimum wage and guilt tripping customers into providing the rest. Yes, ultimately the money that will be used to pay the staff will come from the customer, but the way restaurants do it is dumb. Just pay them more and raise your prices.
