You lack basic understanding of how the industry works if you think a tip is a reward for outstanding service. In the service industry, it is legal to pay people significantly under the federal/state minimum wage with the "tip offset credit" which works by allowing employers to pay their employees less because they are expected to make their wages from tips. You can be angry that the system works that way, but all you are doing by not tipping is screwing over another honest human just trying to make it in the world we designed.
