"I wish I had the nerve not to tip"

Paul Lynde's quote speaks with the sensation of being obliged to do something, even when it is not always preferred. It is most likely that he is referring to the social expectation to tip service employees, such as waiters and bartenders, after getting a service. He expresses a desire to have the nerve to not tip, which might be translated as a desire to break away from the social standard and not feel obliged to tip. This might be a reflection of his own personal feelings about tipping, or it could be a commentary on the expectation of tipping in general. It could also be a reflection of his own financial circumstance, as tipping can be a monetary problem for some people. Whatever the case, it is clear that Paul Lynde is revealing a desire to break away from the social expectation of tipping.
