What are the man and the woman doing?

M: Excuse me. Are you waiting to buy 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 up 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 has let us know. It could be that there aren’ t enough people selling tickets this afternoon. Or maybe their computer is down. I’ m sure the concert hasn’ t been cancelled.
M: I just hope they don’ t run ont 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 avoid 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’ re two more hours before the ticket office closes. Tickets for a good concert are worth waiting for. So I think I’ ll just make myself comfortable.
