Why won't you sit down in a restaurant and announce to the server before you are served that they won't be getting a tip from you because you don't believe in it? That they should find a higher paying job if they aren't happy with the wages the employer is paying them? Huh?
That would be the respectable thing to do considering the servers work for tips, regardless if you believe in them or not, they DO work for tips. So be a responsible adult and let them know beforehand you will not add to their wages.
