听力原文：M: Excuse me, are you waiting to buy concert tickets? W: Yes, I am. So are all these people in front of me. M: Have you been here long? W: About 45 minutes. I've moved forward a total of about 3 feet in that time. M: You're kidding! W: Not at all. There was a couple ahead of me who got so disgusted they finally gave up and left, They said they'd been waiting for more than an hour. M: Terrific. Does anyone know what's causing the delay? W: If so, no one's letting us know. It could be that there aren't enough people selling tickets this afternoon. Or maybe their computer's down. I'm sure the concert hasn't been canceled. M: I just hope they don't run out of tickets before I get up there. W: That really would be annoying, wouldn't it? M: I guess I should have come before lunch. Or has it been like this all day? W: Apparently it has. In fact, before I came. I tried calling to charge my tickets over the phone, just to a void this long wait. But they're not taking phone orders, or checks, or credit cards. It's cash or nothing. And you have to come in person. M: Well, there are two more hours before the ticket office closes. Tickets to a good concert are worth waiting for. So I think I'll just make myself comfortable. What are the man and the woman doing?
