I usually tip 15% or 20% for really good service. If there has been a problem it deoaends on how good the server has been in sorting out the problem. Do not be reluctant to complain if something is not right and judge on dealing with the problem rather than the problem it self. If very good service is given I have been know to seek out the manager and let them know. We feel this help balance all those ackward customers that are never satisfied no matter how good the service.
I have to say we always seem to get better service in the States than we do here in England.
