I did three tours totalling 12 years plus so I have a fair number of anecdotes, some of which have appeared elsewhere and will, no doubt, be regurgitated unless I am howled down. This one is not so much funny as a window into the human psyche.
Guetersloh c. 1970.
Met. Office night duty staff [one forecaster, one observer] were accustomed to snatching 90 minutes charp each in the rest room/coffee bar. Each covered for the other.
One of the forecasters would retire, yawning, and within minutes exit through the ground floor window into his car, out of the gates, down to the nearest layby, and then pleasure his inamorata for a while before returning, back through the window, back into the camp bed, just in time to be "awakened" by the observer with a mug of coffee.
Everyone but everyone [including the snowdrops on the gate] knew exactly what was going on, but the conspiracy of silence was maintained in the hope that he would one night snag his testimonials on the window catch.
