W: Good morning, can I help you?
M: Yes, I hope so. Thank God, you speak English.
W: Well, just a little. What seems to be wrong?
M: I’ ve got an upset stomach. It’ s pretty bad. I’ ve been always with it. Now, I’ ve got a bad headache as well.
W: I see. When did it first start?
M: When I went to bed.
W: Do you think it’ s something you’ ve eaten?
M: Oh, for sure. I’m not used to all this wining and dining.
W: Yes, you’ ve really eaten a lot.
M: You can say that again.
W: Have you got diarrhea? Is it very loose?
M: That’s what it feels like.
W: How often do you have to go?
M: I have to go every few minutes.
W: Are you drinking cleaned water, bottled water?
M: I’ ve had a few sips of water. I felt terribly thirsty.
W: Er. Have you taken anything? Did you bring anything from home?
M: I’ ve got only these indigestion tablets.
W: Can I see the packet?
M: Here you are! Look.
W: Have you taken anything for the headache?
M: I’ ve taken a couple of paracetamols. That’ s all.
W: Do you feel tired?
M: How not? I can hardly keep with my eyes open.
