  #Person2#: I'd like the double cheese burger meal, please. 
  #Person1#: What kind of drink would you like with that? 
  #Person2#: Just coke will be fine.

  #Person1#: That's not a problem, Miss. Will that be it? 
  #Person2#: Yes, that's all. 
  #Person1#: That will be 25RMB, please 
  #Person2#: You got it.
