Sir , your hair is done . Anything else I can do for you ?   I'd like to have a shave .   All right , sir . Would you lie back so that I can shave you ?   Sure . But my beard is rough .   Don't worry , sir . I've never cut a customer . Shall I trim your moustache ?   Yes , please .   Now , I've finished . How do you like it ?   Wonderful . How much is the cost altogether ?   20 dollars .   Here you are . Thank you , bye-bye !
