One of the signature blocks on the clearance chits was for the 'Station Bicycle Store'. No-one at a unit where I was serving knew where that was, or even whether there was such a thing on the station...
But some helpful soul had amended the crew room phone directory with 'Station Bike Store.......(extn. no)'.
Except the extension was for someone else..... OC WRAF eventually complained to her boss about people ringing her to ask "Is that the station bike store"?
