That is when you go to the manager and ask for a refund or a price reduction. You don't fault the waitress. So by your logic if you see a movie you don't like you blame the ticket person at the box office. 
I would shit and cum on your food if I had the chance.
Also if you can't afford more than 10% tip you should not go out.
The ticket seller does not demand a tip!
You just pay and get your ticket.
Waiters and waitresses you pay for the food, then they still want bucks on top of that.
That changes the rules W88
I am not scared to tip 10% even more if I felt it worth it.
If I dont feel that the waitress deserved it why must I be extorted into giving a tip?
For me to have a good time the food must be good, the service must be good, the setting or mood must be good and my company must be good.
They are in controll of the first 3.
You want a good tip? you want my business? make sure it those things are there.
Oh and I dont tip for food covered with poop and semen so no tip for you bro
