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