For those of us who dislike compulsory tipping, we want the restaurant (or hair salon, or nail 'place') to charge more if that's what it takes. We want to know how much restaurant X charges for a hamburger and fries with a beer just as we would want to know how much the plumber is going to charge to fix the hot water in our homes ... including tax and any other add-ons that go with it. The customer wants to know what a provider charges for a service, in total; with that knowledge, s/he decides if the service/product is worth it or not. If I buy a guitar from Elderly Instruments or Dave's Guitar Shop or MF, I don't want to be quoted a low price for the guitar and then have to work out for myself how much extra I need to pay so that the sales assistant can afford food for the weekend. I expect that his employer has already factored in his salary with the price of the guitar. In most of the commercial world, this is common sense. In some areas of the service industry in the US, unfortunately, it isn't.
