Would you like some more coffee ?   No thanks . I'm full . We need to find our waitress and get our bill .   Good luck finding the waitress !   The service this evening has kind of sucked . Is that our server over there ?   I'll go get the check , since our server doesn't seem to be headed this way .   Good . I'll just stay here until you get back .   So the total is $ 36.00 for our dinner .   How much of a tip do you think our waitress deserves ?   I wonder if no tip would be appropriate in light of the service .   I kind of feel the same way , but they may have just been really short-staffed tonight .   I think that we should leave 10 % .   $ 3.60 will be the right amount for the tip .
