It can work in your favour, The gliding club I was with in RAFG came across a cable crimping tool that it was deemed could be useful on winch cables, but it was not complete. Through the supply system. we put in for a new tool from the good folks up near Carlisle and a new tool duly arrived, Then they woke up the fact that the Station had no need such a device and demanded it be returned. So we sent back the old one and honour was satisfied, we had one and the supply computer had one. Simples
