I can tell you why the whole Service Charge Inclusive irritates customers. Its false advertising. You are increasing the cost of the meal but not reflecting it on the menu. People find it dishonest like every other time in our lives where we are told a price, but then we get hit with a fee. Ask bank customers about it.
Just be honest, the meal needs to cost more because the cost of production is more.
