There's always someone worse off than yourself. One of my colleagues has just received a circular memorandum from his director telling all staff that from now on there'll only be blue pens available in the stationery supplies. He tells them that it's a wasteful duplication to be stocking both black and blue pens. By my reckoning, even taking into account any price differentials and increased discounts for volume the annual saving couldn't be much more than half the cost of his time in thinking up this nonsense.
This isn't normal behaviour. Even by my jaded experience this isn't natural. There's probably some evil bastard somewhere including this sort of thing in their library management courses. The UN War Crimes Committee should be scouring the library schools of the world to put a stop to it.
And what would we then do with the poor damaged creatures left behind to fend in the wild with nothing more than a library manager's salary to support them? I suggest that they could undergo a comprehensive course of retraining by smacking them about the back of the head with a plank. Or they could be humanely euthanised by smacking them about the back of the head with a plank. Whatever course of action is chosen, smacking them about the back of the head with a plank looks like a sound option.
