In a previous job i was contracted to install 500 new desktop PC's. Every new desktop came with a new power cable which was slung in to a large box. As these new desktops were replacements there was already an existing power cable there so the new ones weren't needed.
One day I found the PAT guy sat at the box of 500 power cables looking rather bored. He had carried out a PAT on every single cable. Why? Because he was told to PAT everything! Nice little earner
