W: Good afternoon, sir. What can I do to help?
M: Oh, I have a terrible cold. Apart from that, I have a headache. Can you suggest something I can take to relieve the pain?
W: Don’t you have a prescription?
M: No, I haven’t gone to see a doctor.
W: Are you allergic to any type of medication?
M: I don’t know exactly. I think that I can take most drugs.
W: OK then, I recommend this brand for quick relief.
M: Will this really help?
W: According to the label, yes. But if that doesn’t help, then drink a cup of hot tea along with some honey. There’s no miracle drug to cure a common cold.
M: Which are the best headache tablets?
W: We have a number of them. They are all very good.
M: Can you sell me penicillin?
W: Sorry, sir. I cannot sell it; you must first get a doctor’s certificate or prescription.
M: Well, then, give me some boric acid.
W: All right. This is a common medicine.
M: Do you have any cough syrup and lozenges?
W: Yes, of course.
M: That’s great.
W: Here you are. The instructions on it tell you how to take it. Make sure you read them carefully.
M: Thank you for reminding me.
W: Please pay special attention to this cough syrup. Shake the bottle before you take it.
M: Thank you very much indeed.
W: Anything else?
M: No, thank you.
W: You’re welcome. I hope you will recover in no time.
