Madison Square Garden. Can I help you?
Yes. Do you have any more tickets for the concert on Friday night?
Do you mean the Rock'n'Roll Revival Show? Yes, we still have some $30 tickets left.
Great. OK, and is the box office open now?
Yes, the box office is open from 10:00 am to 8:00 pm.
Oh, by the way, what time does the show start?
It starts at 8:00 in the evening.
And what time does it end?
Well, there are four bands, so it'll probably end at about midnight.
Thanks a lot.
