Krock, KPA.

I'm torn... Would a Ferrengi prefer a Klingon CPA, or would they always worry about an "honor killing" if the books were off? On the other hand, would a Klingon look at the tax code as a battle of wits, trying to justify exemptions and maximize profit margins to "win"?

I think that a Ferengi wouldn't want a Klingon accountant because the books would be scrupulously honest. A Klingon accountant would see honest book keeping as a point of personal honour, where the Ferengi ASSUME that the books are cooked, so long as they are the ones doing the cooking.

"Those who create false ledgers have no honor..."
