There was just one lady in front of me, an Asian lady
who was trying to exchange yen for dollars.

It was obvious she was very irritated.

She asked the teller, “Yesterday, I get two hunat dolla fo yen. Today I only get hunat eighty? Why it change?”

The teller shrugged his shoulders and said,

“Fluctuations.”

The Asian lady says, “Fluc you white people too!”
