It's Already Begun

A tourist from Hong Kong walks into a London Exchange Bureau with HK$500 and asks for £GBP. The teller checks the day's rate, and hands over £35. The grateful tourist says, "Thank Velly mutch! Velly kind!" and walks off to Kings Cross.

The next day, the Hong Kong guy goes back, with another HK$500 and hands it over. The teller checks the rate, and hands over £50. The Hong Kong guy is very happy, and quickly pockets the cash and disappears, chortling to himself, "This English velly bad math. Ha, ha, ha, ha."

The following day he returns, again clutching HK$500 in crumpled notes. He hands it over to the nonchalant teller, who checks the rate, and hands over £20. The Honkonese man does a double take, recounts the notes, and fixes the teller with an incredulous stare. "Hey, yesterday I come wif money, you give many many pounds - fifty! Day before, you gif firty-five. Today you give onry twenny. Why you do to me like this?"

The teller replies calmly, "Fluctuations Sir."

The apoplectic tourist screams back, "Fluck You Brits Too!"
