Input:  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 !
