Exactly! Also, tipping (actually the lack of tipping) allows the customer to provide monetary feedback on the quality of the service.<p>I can choose to tip nothing as a &quot;fuck you&quot; for bad service.<p>In fact, I actually once deducted 18% from a bill I got at a restaurant where the service was so poor, we had to carry our own drinks and food from the kitchen to where we were sitting.<p>I left a note and explained that I was tipping myself for that experience and left 18% less than the bill was.<p>That actually worked and the service we have had from them since has been stellar!
