1. When you have a stomachache.
Doctor: Please come in. What seems to be the trouble?
Patient: It's my stomach. I think probably I had too much at supper yesterday evening.
Doctor: Can you tell me what you had for supper yesterday evening?
Patient: Seafood, roast duck. Oh, a great variety of things, I can't name them exactly.
Doctor: Have you vomited?
Patient: Yes, I have vomited three times and made several trips to the bathroom last night.
Doctor: I see. Now you have to get your stools tested. I'll write out a slip and you can take it to the laboratory. Wait for a while and pick up the report, and then bring it back to me.
Patient: Alright, doctor. I'll see you later.
Doctor: See you later.
Patient: Here's my report, Doctor.
Doctor: Take your seat, and let me have a look. It's nothing serious, only indigestion due to too much oily food. I will prescribe you some medicine for it to make you feel better. I do advise you to avoid oily food for the next few days.
Patient: I will follow your advice. Thanks a lot.
Doctor: You are welcome.
