Remind me why I should care about the wage structure of a restaurant’s employees? I don’t care about the pay scales and Ts & Cs of public transport workers, or security guards, or shop workers, or Big Issue sellers. Why must I care about remuneration of waiters?

Service is clearly an integral part of a meal in a restaurant. I suppose if it is seen as an optional extra I could tell the restaurant I don’t want the service on the side. How would that work?

And how about hairdressing? Apparently that is a tipped service in USA. What exactly is the tip for here? You cannot deliver a haircut without actually cutting the hair.
