I have a new favorite game

I love diners. But as you know I have a problem with the lack of attention I get at them. So I developed a new game this morning. A game that only works when you pay with credit cards, which I do. See, when I feel I have been wronged at a diner, (and by that I mean I do not get my coffee refilled in a timely manner or do not get my toast WITH my eggs) I am going to give a tip with a random amount of change added to it… for example, instead of giving $2.00, I will give $2.34. BUT I will add it wrong to the tip and walk out before anyone notices. Let them freakin figure it out.
