What is the woman doing?

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 30 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.
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 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 avoid this long wait. But they’re not taking phone orders, or checks, or credit cards.
M: Well, there’re two more hours before the ticket office closes. Tickets for a good concert are waiting for me. So I think I’ll just make myself comfortable.
