One thing you can be absolutely sure of. If you add the tip to my bill, you will never get another penny of my business. I tip for performance of service ONLY and "so so" service may only get a 10% tip up to "superior" service which will get 20% guaranteed (sometimes maybe a likkle more )

I get so tired of the "gimme gimme" attitude concerning money. You want my money? Be willing to work for it just like I had to in order to have it. No one gave me money for doing nothing so I am just passing on that life's lesson!
