But to the point of the person you replied to, on the busy days, there would be two of us working. We were free to split labor however we liked. We made far more tips when it was my attractive, female, coworker taking orders and interacting with the customers, and me scooping, than the other way around. People absolutely do tip differently based on their biases regarding the worker they are interacting with.
But almost any significant policy or social change will have an impact like that. You have to basically give up on fixing anything if you're not willing to impact anyone.
And if the answer is no, why not? I’m providing a service after all am I not?
I'll admit up front that I'm simply not going to see eye-to-eye with anyone who thinks a system is acceptable or sustainable that requires subjugation of many for income maximization for a very few. There's FAR too much capital in play for me to feel bad at slightly less comfort for some if it means drastic reduction in suffering for so many.
