Tipping is why I carry cash for restaurants I don't need to let the server know the number of audible beeps I'm hitting on the machine as they loom over me to guilt me into that 25% tip for whatever ungodly reason exists on the machine.

I think I'm in the smallest minority, but I haven't tipped in close to a decade. When people ask me why, I answer with the question "when was the last time you tipped your grocer l, fast food window attendant or the person at the hardware store that brought out your 100lbs of lumber? " answer is always never and I say exactly.
