This is the time of the year that we receive several gift certificates to restaurants. As a rule, they are less than the bill so leaving a tip is no problem. However, we just received one that is substantial, far more than we could ever eat or drink. We spend much time with people and like to go out to enjoy ourselves alone, like with this certificate.
Question: If the bill is, say, $175.00 and the certificate is for $250. Does the $75 go to the wait staff, or should we leave a cash tip?
