As I have posted here before, if they automatically add 15%, that's what they get, period. I don't care what the server says. I think I recall the server said something similar the last time we were at Sublime. Service was excellent on that occasion. Perhaps it is the self-fulfilling prophecy that I have stated before--it basically encourages bad service, as the servers know they are going to get the same amount, regardless of how they perform. And it's less than they get other places. Therefore, good servers vote with their feet and move on. It makes me think about whether to go back there again, as I have enjoyed it very much in the past.
