This may stir up a little dust storm, but I worked as a server during university and worked hard, but made very good money (mostly tax free), if I had received 18% on every bill I would have been kissing their hands as they exited. If I get great service I tip 20% or more, average 15%, bad service - I will write on the bill No service/no tip - but it has to be bad service due to the server ie: not because he has too many tables to service properly or the kitchen is slow. I think it's important to recognize that you aren't tipping because you are cheap as opposed to because you had bad service (I think we will all agree that bad food is easier to digest than bad service, especially on vacation) I will absolutely recognize great service but equally will recognize (no tip) bad service. I do agree with, and consistently do "tipping up" for meals and drinks OOP. My ten cents (CDN) worth...
