George：Don’t cut it too short on the sides and the back. Just trim it a little。
Barber：How about on top?
George：You can thin the top out a little, just a little。
Barber：You got it。
George：Say, my hair is kind of oily. Dandruff bothers me a lot. I’ve tried several shampoos, but to no avail. Could you recommend something effective?
Barber：Well, have you tried Head and Shoulders? I recommend it to all of my clients with your problem and they think it’s great。
George：Thanks. I’ll try it。
Barber：And you can try Vidal Sassoon’s hair tonic. It’s used after you wash your hair. It’ll keep your hair clean-looking and oil-free。
George：I’ll try that, too. Thank you。
Barber：It’s done. That will be five dollars and thirty cents。
