Mrs. Chang Takes A 500 Yuan Bill To The Bank To Change For Dollars

The teller makes the calculation and gives her $80.44.

Mrs. Chang returns the next Friday and puts a 500 yuan note on the counter. The teller puts down $79.94.

Mrs. Chang says "Last week you give me $80.44, but now I get $79.94. Tell me why it changed!"

The teller showed her the exchange rate sheet and said "FLUCTUATIONS!"

Mrs. Chang got red faced and indignant, shoved her finger in the teller's face and said,

"Oh yeah, well FLUC you white people too!"
