answer: #Person1# hasn't realized the meaning of 'go Dutch' and failed to find Dutch food. Then #Person2# tells #Person1# it means to split the bill.
documents: #Person1#: ok, so what have you got in store for me tonight?
  #Person2#: I'm really sorry, Ethan. I tried so hard, but I'm afraid I could't find a Dutch restaurant in town. The best I could do was a German one about 15 minutes from here.
  #Person1#: what? I don't understand.
  #Person2#: I though you said you wanted to have Dutch food?
  #Person1#: Oh! Ha-ha! That's not what I mean when I said'go Dutch'!
  #Person2#: Huh? What were you talking about, then?
  #Person1#: 'going Dutch'means to split the bill, silly!
  #Person2#: oath. . . that makes so much more sense! Ha-ha. Well, great, I don't like German food anyway!
