Why does the man want an early appointment?

M: I have to have an appointment first thing in the morning. The doctor wants to do me tests and
I mustn’t eat for twelve hours before that. I’m right, aren’t I?
W: Yes. She said the best way is to go without breakfast and come in early.
M: Yeah. Then I can have a snack and not miss too much time at work.

M: It leaves in five minutes and we can’t get all the way back to the check-in—sure you put it inside your passport, like you usually do.
W: And that’s right where I always keep it, in the side of my handbag, but the boarding pass isn’t there. I didn’t give it to you on hold, did I?
M: Not this time. I’ve been holding the newspapers all the way!
