You might as well state: "I hate commissioned sales. How can we end it?" You might find a wider audience in agreement with you.

Personally, I like tipping. In high school and college, I worked in restaurants as a waiter and busboy. From personal experience, I can tell you that some people make a very good living from tips and some don't. The reason is some are better at their job and some aren't. I sincerely enjoy acknowledging better service with my wallet. I am less excited about acknowledging poor service with a lesser tip, but do it when I must. I have eaten in other countries where tipping is not part of the culture and have found service to be generally indifferent.

You're going to pay for the cost of the service one way or another, since no one works for free. I prefer one way. You're entitled to prefer another. Maybe there should be a choice; flat 18% service charge or tip what you think the service was worth.
