Bureau de Change
Japanese guy goes into a bureau de Change with 2000 Yen. He exchanges it for $77. He goes away and spends it, and goes back the next day with another 2000 Yen and the cashier this time gives him $62.
He looks at his money and says, ‘Why you give me $15 less today?’
The cashier replies, ‘Fluctuations.’
To which he replies, ‘Well, fluck you Amelicans too!’
