Guilty until proven Innocent

Warren is the software support personnel for System S sold to Client B. This position was previously held by Sandy who has since moved to a different project. Band is the hardware support personnel for the same system.

One day, a problem occurred in System S and Client B calls Warren who could not provide an answer. So, Client B calls Sandy. Sandy answers the questions posed and re-direct Client B to Warren as more information is needed to find out the cause of the problem. Client B decides to call Band.

In the following weeks, Warren refuses to speak to Sandy. Warren tells Sandy, "I have the right not to speak to you.", and that is all that Warren will say.

Months later, Warren started to speak to Sandy again. Soon, Sandy asked Warren "Why did you refuse to speak to me a few month ago?". Warren replies, "I thought that you called Band on your own to go to Client B to solve the problem. Recently, I found out that it was actually Client B himself who called Band and not you.".

So, you are Guilty until proven Innocent.
