Why is it that you people who never tip you're servers at restaurants are usually the ones that run them back and forth to and from their table like dogs playing fetch? You come in knowing you are not going to tip but see to it that your server spends a majority of their time catering to you. A servers main income is their tips, so do you honestly think it is fair that you run them ragged and keep their attention off of the people who actually do tip them? This question is directed to people who never tip regardless of the service they get. Not the ones that don't tip due to bad service. That's understandable.
