While 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 yuan for dollars. It was obvious she was a little irritated.

She asked the teller, "Why it change? Yesterday, I get two hundred dollar for yuan. Today I only get hundred eighty? Why it change?"

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

The Asian lady says, "Fluck you white people too!"
