Listen to a conversation between a student and an employee at the box office of the university theater.(man) Can I help you? (woman) I hope so. The usher told me to talk to someone at the box office. (man) Okay…(woman) Well, I have a comp, a complimentary ticket for this performance, or at least I thought I did, but someone else is sitting in my seat.(man) Um, it could be the ticket was invalidated and the seat was reissued to someone else. (woman) Huh?(man) Well, did you call to confirm you were coming?(woman) Well, I told Sarah, my roommate, I\'d be coming. She\'s the one who gave it to me. She said cast members get two free tickets each.(man) Yes, but it\'s the theater’s policy that comp tickets must be confirmed by phone, email or at the box office no later than 48 hours before performance time.Otherwise, we were free to sell the ticket and I suspect you didn\'t do that. (woman) Um, no, I didn\'t realize.(man) You see, many of those comp tickets don\'t get used, without this policy.Well, why lose out on the chance to sell more seats? (woman) Make sense, I guess.(man) It\'s printed clearly on the back. (woman) I guess I should’ve read the back of the ticket.(man) Well, your roommate should’ve told you that, cast members should be aware of the policy.(woman) Yeah, but they only called her for the part last week when the other actor got sick.(man) I see. Well, there are a few empty seats up in the rear balcony. We can offer you a ticket there, free of charge.(woman) At least it\'s not totally sold out. But I was hoping to sit up front, the seat she gave me is in the first row. I wouldn\'t mind paying for it.(man) I\'m afraid those are sold out. (woman) Oh…(man) The view from the back isn\'t bad at all. I’ve sat there myself and you can see everything just fine.(woman) But I promise Sarah that I\'d be there for opening night. She\'ll be looking for me in that front row seat.It\'s her first time on stage and she\'s been so worried about messing up. I\'ve been rehearsing with her every night.(man) How about this? Take this balcony seat for now and at intermission, if there have been any no shows on the lower level, we can switch you then. (woman) No shows?(man) You know, sometimes people decide at the last minute not to come for whatever reason.Some even leave it at intermission if something unexpected comes up, or maybe they just don\'t like the show.I\'ll ask the usher to check for empty seats when his first act ends. And if there\'s anything free up front, it\'s yours.(woman) That\'s really nice of you. And Sarah doesn\'t even come on stage until the second act.(man) Of course, I\'m not promising anything. (woman) I understand. See you at intermission.
