When auditing time came around we just shoved the "snaps" and "inactive fruit" in the desk drawers...
Actually, I have never been a very good employee. For this reason, i might mistake "inactive fruit" to be one of the former hall monitors trying to implement the "efficiencies". Hard to say where I might stuff it (or him).
That being said, the most efficient way to measure the success of a new program like this is by it's acceptance and implementation in the work force. If it actually aids in productivity and focus, they will warmly receive it.
I somehow doubt this to be true in this particular case.
