I was working as a teller at a bank when a Japanese woman walked in. She comes to the counter with a small stack of ten-thousand yen notes. "Hi, can I help you?" I said. "Yeah, How much American dorrah I can get for hundred thousand Japanese yen?" she asks. Looking up the information on the ever-changing database of currency valuations, I tell her, "By today's numbers, you can get eight hundred and fifty dollars for one hundred thousand yen." Bewildered, she asks, "What? I come here six month ago and you give me one thousand dorrah for hundred thousand yen. What big deal?" Not wanting to explain to her the complexities of the global currency market, I simply shrug and say "Fluctuations."
Clearly taken aback, the woman picks up her money, looks at me, and says, "Yeah, well FRUCK YOU white people too!"
