Input:  Person1:     Hello , may I help you ? 
 Person2:  Yes , I need some more cash for my visit in China . May I cash a traveler ’ s check here ? 
 Person1:      Of course . We would be happy to cash it for you . 
 Person2:  I was going to cash it at the hotel , but one of my friends said that banks always give better exchange rates . 
 Person1:      Well , any bank will cash it at our present traveler's check buying rate , for which we ’ re somewhere cheaper than hotels because of the service charge . You see , hotels really aren ’ t in the money exchange business although they will cash traveler ’ s check for their guest . 
 Person2:  You mean there is really not that much of a difference . 
 Person1:      No , madam . Not very much . 
 Person2:  Well , may I cash these three checks for 100 dollars each ? I think that will be enough . 
 Person1:      Yes , I'll be happy to cash these for you . Would you please countersign them here ? 
 Person2:  Ok .
