A、They are trying to call someone. B、They are attending a concert. C、They are waiting in line. D、They are canceling reservations

M: Pardon me, madam, but can you tell me where I can find the line for concert tickets this Saturday?
W: It’s here. I’m waiting and so are all these people in front of me.
M: I want to buy tickets, too, but I don’t have much time. Have you been waiting long?
W: I’ve been here about one hour and so far I’ve moved a total of five feet in that time.
M: You’re kidding!
W: I’m not. There was a young man waiting in front of me who got so frustrated that he finally gave up and got out of here. He said that he had been in line for over two hours.
M: Great. It shouldn’t be taking so long. Do you know what’s causing all of this?
W: I have no idea. Maybe they don’t have enough people here to sell the tickets. I just hope that the concert hasn’t been canceled.
M: I just hope there are still tickets by the time I get up to the counter.
W: It would be so annoying if that happened.
M: I wish I came here before lunch instead of now. I thought I had enough time to eat first. Has it been like this all day?
W: Apparently so. I originally wanted to call and do all of this over the phone, but they said they weren’t taking phone orders.
M: There are three more hours until the ticket booth closes; I guess I better stay. Tickets to a good concert are worth the wait.
