A: Would you like some more coffee? B: No thanks. I'm full. We need to find our waitress and get our bill. A: The waitress is bringing the bill right now. B: This waitress has really been on top of things, hasn't she? A: Yes, this waitress did a great job. B: OK, let's see what the damage is. The total for our meal is $36.00. A: What do you think would be the right amount to leave for a tip? B: Fifteen percent is a normal tip, but she really did a great job. What do you think about 20 percent this time? A: Yes, 20 percent would be perfect. B: Her tip will end up being $7.20 plus the bill of $36.00. The total will be $43.20. A: Yes, that was one fantastic meal! B: I agree. Maybe we can come back again next week.
