Indeed, that restaurant had a 18% gratuity for a party of six or more. Good thing I was eating alone. :P
Washington sales tax is 9%, so that would come out to 18% (give or take a few cents). I think that's a pretty good rule of thumb, actually. :P
One thing I'm not really sure about though is how you indicate the tip in the case where they take your credit/debit card and then bring the check for you to sign. Do you write down the amount there and then they'll deduct it in full? Or something? :P
