She really fucked this one up

Tipping exists the way it does because of the nature of service industry. Waiters are typically much friendlier and more helpful than employees of any of business you utilize because they need to earn a tip. Businesses try to ram friendliness down their employees throat but it's impossible to make a walmart employee care about the customers, it's more artificial. As far as money, the mom-n-pop Italian joint i worked at would have never stayed afloat if they had to pay their waitresses minimum wage. That doesn't apply to large franchises but it was true for us. People came because the food was cheap and the tip felt like an exchange between the patron and waiter with nothing to do with the restaurant. If we raised our price we would have had no identity to compete against every other joint charging $9 a plate. if you eliminated tipping it wouldn't matter how hard restaurants tried to enforce policy, the quality of service would decline rapidly because they wouldn't give a fuck about hurrying to get your cake.

Also, you seem to be a very angry person and I don't see why. You said yourself you spent $463 on 3 plates of food but you want a waiter to, 'get a different job,' because, 'you bill $500 an hour.' You brought up socialism, so let's talk capitalism... If you have this mentality about tipping and it's well-known by the wait staff, should they draw straws to see who has to serve you, knowing they'd make more money on a different table? I'm not for handouts but I'm not going to be the guy that no one wants to serve because I stuff my face with $500 and then shame the help for hoping they can wait on me hand and foot to provide service worthy of $15 for an hours work.
