answer: #Person2# checks three pieces of luggage and #Person1# tells him only two pieces of checked luggage are allowed. #Person2# is angry about the extra charge of an additional suitcase and the cost is more than #Person2#'s round-trip ticket.
documents: #Person1#: Next please! Hello sir, may I see your passport please? 
  #Person2#: Yes, here you go. 
  #Person1#: Will you be checking any bags today. 
  #Person2#: Yes, I'd like to check three pieces. 
  #Person1#: I'm sorry, sir. Airline policy allows only two pieces of checked luggage, at twenty kilograms each, plus one piece of carry-on luggage. I will have to charge you extra for the additional suitcase. 
  #Person2#: What? Why! I am taking an intercontinental flight! I'm flying sixteen thousand kms! How am I supposed to only take two, twenty kilo bags? That's absurd! 
  #Person1#: I am sorry, sir, there's nothing I can do. You cannot board the flight with that large bag either. Carry-on bags must fit in the over-head compartment or under your seat. That bag is clearly too big. 
  #Person2#: Now I see. You charge next to nothing for an international ticket, but when it comes to charging for any other small thing, you charge an arm and a leg! So tell me, miss, how much will I have to pay for all of this. 
  #Person1#: Let's see. . . six hundred and twenty-five US dollars. 
  #Person2#: That's more than my round-trip ticket!
