Understanding English

When Nancy was going to Florida, she had a bundle of Euro she needed to exchange, so she went to the currency exchange window at the local bank. The line was short. Just one guy in front of her... an Asian guy who was trying to exchange yen for dollars, and he was more than a little irritated!

He asked the teller, "Why it change??

Yestoday, I get 2 huna dolla fo yen.

Today, I get huna 80?? Why it change?"

The teller shrugged her shoulders and said, "Fluctuations."

The Asian guy says, "Fluc you white people, too!"

I wonder if Nancy managed to change her money?
