A Supply Officer I know was audited. It was noted that the store was only half full. Clearly, if half full was enough then a smaller building would be more efficient.
True but who would pay for the new building?
Who would buy the old large building?
OK, maybe if a new large building was required then a swap could be arranged.
This overlooked some obvious points. The present building was in the right place but this may have been unsuitable to any other purpose. Crucially however it was the TOP half of the building that was empty. All the racks wer filled to their safe working height given the weight and bulk of the stores.
