Also, do you realize that in most of the low-class restaurants you go to, servers split their tips and have to give the kitchen staff a cut as well?

You seem very concerned that lazy servers who don't work hard, don't get paid. But what if they get paid all the same? Instead of a server getting $5.00 less from you, every server in that restaurant gets 25 cents less? In other words, you aren't punishing them at all. They won't even notice the difference.
