A: Do you want some dessert? B: No thanks. We just need our check. Have you seen the waitress? A: Here comes our waitress with our check. B: The service here has been really great, don't you think? A: Yes, the service was quite good. B: So, let's look at the check. The total is $36.00. A: How much do you think we should leave for a tip? B: Usually people leave 15 percent, but this was exceptional service. I am thinking that maybe 20 percent would be appropriate. A: I agree that 20 percent would be just about right. B: OK, so that will bring her tip to $7.20. Add it to the $36.00 and the total is $43.20. A: Yes, what a nice dinner that was! B: We'll have to make sure to come back here again real soon.
