A: Do you want some dessert? B: No thanks. We just need our check. Have you seen the waitress? A: Where is our waitress anyway? B: Yes, the service hasn't been the best. Is that our waitress over there? A: I'll walk over and get the bill, since I don't think the waitress is coming over here any time soon. B: Good idea. Just bring it back and we'll figure it out together. A: So the bill is $36.00. B: How much do you think we should leave for a tip? A: My first inclination is to leave nothing for a tip. B: I agree, but we don't really know the whole story. There may have been problems in the kitchen beyond her control. A: Let's leave 10%, so that we at least leave something for the service. B: I agree. We will leave $3.60 for the tip.
