A、He doesn’t consider much about customers. B、He can’t offer any practical way of promotion. C、He doesn’t deserve the promotion

W：Right, I guess you have some ideas for our promotion.
M：Well, first we must win over the medical circle, so I think we should launch a campaign in all the specialist medical journals to promote our prescription drugs, antibiotics and so on.
W：Sounds like a good idea.
M：Then about TV commercials.
W：Just a moment. Are you sure we’re allowed to advertise medicines on TV?
M：Of course, yes, provided they aren’t drugs which need a prescription. We can advertise over-the-counter products. Then I thought we would get users of our products to support them.
W：Hold on. It’s forbidden to claim any positive cure for a disease. And we mustn’t offer any drugs for illnesses which should be treated by a doctor.
M：OK. What about this— a series of full page newspaper ads with the message that most doctors consider our products the best?
W：That depends on whether it is true. We can only refer to doctors’ preferences if our claim is supported by facts and figures.
M：Well, I’m sure it is. Here is another suggestion. We could offer to refund the purchase price to anyone who is dissatisfied with one of our products. It’s possible to do that, isn’t it?
W：No, I’m afraid not. Manufacturers of medicinal products aren’t allowed to offer a refund in their ads.
M：Well, it looks as though I’ll have to come up with something else. I never realize the regulations are so rigid.
