What I do for a living, requires a hell of a lot of knowledge, arcane as it is. I don't get gratuities unless you count a Christmas fruitcake or popcorn sent out communally to the business I work for. I pay Darlene extra for doing my hair, not because tipping is required, but because I like her and she should get paid a hell of a lot more than her employers pay. That should be the issue here. People in the service industry deserve to get paid a healthy wage, not rely on the good will from stranger like a pathetic beggar
