Story for Shasha

An American company instructed their new Japanese supplier that the parts they had ordered should conform to the US firm's exacting quality standards - 99.9 per cent conformity to specification. Confused, but determined to comply, the Japanese firm deliberately shipped one faulty component with every 999 perfect ones. A note accompanied the shipment stating that they were unsure why the customer wanted 0.1 per cent failure but they were happy to oblige.
