answer: #Person1# asks Mr. Lee if he can volunteer to give up his seat because the flight is overbooked. Mr. Lee will volunteer to receive a free ticket.
documents: #Person1#: Good evening, Mr. Lee and thank you for choosing our airline. We have just discovered that this flight is overbooked. Would you like to volunteer to give up your seat?
  #Person2#: Overbooked? Give up my seat? I don ' t understand.
  #Person1#: From time to time we have a situation in which there are more passengers than there are seats on the aircraft. That ' s overbooked.
  #Person2#: I know what overbooked is, I just don ' t understand how that could happen?
  #Person1#: Actually it ' s a common practice to overbook, as passengers often don ' t take their flight as scheduled. Most of the time there is no problem but today, more passengers arrived than we have seats,
  #Person2#: So who has to stay behind?
  #Person1#: Well, first we ask for volunteers. If someone like yourself volunteers, they receive a free round trip ticket to be used within one year. If no one volunteers we just have to select someone.
  #Person2#: Ok. I ' ll volunteer. I could use a free ticket!
