What is the patient suffering from?

M: If you’ll just have a seat, Ms. Thomas, I’ll look into your mouth. Open wide! Em, still a bit red and swollen. Have you been taking the tablets I prescribed and cut down on the cigarettes?
W: Yes, doctor. It’s actually not half as sore as it was.
M: Em, yes. Your voice sounds better as well. Just take the tablets for a few more days and we’ll have another look then.

W: Good morning, I’d like two of this, please.
M: Is that in color or black-and-white?
W: In color, please, just as it is.
M: Of course. You do realize color is more expensive, don’t you?
W: That’s fine, I’m not bothered about the cost.
M: It’s a nice drawing. Did you do it?
W: No, no. Actually, I got it from an art book.
