M: Excuse me. One ticket, please. Do you give students a discount?

W: We do, but the museum will dose in twenty minutes. We stop selling tickets at 3: 30. It's 3:40 now.

M: Could you possibly let me go in for a quick look? I can pay the full price.

W: I' m sorry, I can't. And it's not really worth it because you won't be able to see everything within twenty minutes. You can come back tomorrow morning. The museum opens at nine o' clock.

M: Well, in that case, I'll do what you say.
