I'll be OK if I ever have to entertain wasps

To prevent thefts we've put most of our public PCs into chunky metal safes. Two unprotected PCs' going walkies from Senebene Library the other week illustrates the need. This is not without its problems, especially when the time comes to try and sort out a problem with the hardware. There is a definite knack to getting the safes open and virtually all the front-line staff have agreed that I'm the only person on the books what has it. Which is usually fine, if inconvenient, though it makes a splendid excuse for getting out of the office when nerves are particularly frayed. Today it isn't fine as I seem to have lost the knack at Noddy, neatly snapping the key in the lock at the first turn. There was only me and the PC guy there so I can't even blame the staff for distracting me. Luckily the bloke who makes the safes was very understanding and only took the piss a little bit.
