my fellow programmers

You know, I'm not really surprised when business people tell you the outcome and expect you to instinctively know that it's right or wrong. It's obvious to them.

However I expect much better of my fellow developers. We should know that the outcome is exactly what the system has been told to do; there is no "wrong" answer so long as we get an answer.

Getting the answer that the business wants on the other hand, is our meat and milk.

So do not tell me that this is what it's producing and expect me to know if it's correct, as though by magic.

Also: it wouldn't kill you to say 'please' and 'thank you' once in a while. Seriously.
