answer: #Person2# wants to check three pieces of bags but #Person1# tells #Person2# only two pieces are allowed so the additional suitcase must be charged, which will cost more than #Person2#'s round-trip ticket. #Person2# gets enraged.
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 CMS! 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!
