One of the monitors on Senebene Library's counter died yesterday. I tried jerry-rigging a replacement, but that didn't work so the staff had to wait until maintenance came out with a replacement. Unfortunately, try as they would, they couldn't open the security cage of the PC so they couldn't plug in the new monitor. They tried every key in the place with no joy. I've just popped in, had a go myself and also failed. I wondered if the key had bent so I came back to pick up my copy of the key. Lo and behold, there was their key. I'd absent-mindedly stuck it in my pocket yesterday.
Readers will have already come to the conclusion that the systems guy is a prat; this will come as confirmation for them as need it.
