Real Life Example of FX

I was at my bank today; there was a short line.

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 a little irritated . . .

She asked the teller, "Why it change? 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."
