  #Person2#: Yes, I would like to exchange some money.
  #Person1#: what currency would you like to trade in?
  #Person2#: I would like to exchange Chinese RMB for American dollars. Do you accept $ 100 bills?
  #Person1#: No problem, we can accept any denomination. How much would you like to exchange today?
  #Person2#: Well, that depends on the rate. How much is the RMB trading at today?
  #Person1#: It's a shame you didn't come a little earlier, the exchange rate was reset yesterday afternoon. The American dollar is now worth 7.45 RMB. It was much lower yeasterday. If you would like to sell RMB, we can give you a rate of 7.35. Will that be all right?
  #Person2#: I guess, here, give me 5, 000 RMB worth please. I might as well exchange a little extra. Who knows what the exchange rate will be tomorrow!
