Following on from Lonicera's recent post about objects that were once commonplace in offices etc, I wondered if anyone has any interesting or amusing stories to tell about initiation tricks and suchlike - usually played on young newcomers to work. I suspect the practice died out long ago and wouldn't be tolerated these days but some of you might have experienced it in the 1950s/60s.
In the drawing office I remember apprentices being told to go to the stores and get a glass hammer to tap in drawing pins - or to go to the basement and find a file that didn't exist.
