Nothing better than going into SHQ in your "clean" wet weather jacket, stinking of either fuel or better still de-icing fluid, and watch the shinies start wrinkling their noses up, you get priority treatment once they realise you are the source of the smell!
Or another the classic memo from OC Supply sent out around Oct/Nov time every year - saying that he has noticed an increase in the consumption of batteries, especially torch batteries. As an engineer you know it is darker longer in winter than it is in summer, obviously the flight line is not equipped with electric office lighting!
Or the same scam from MT complaining that the line L/R fuel efficiency has gone down now winter is here, wouldn't have anything to do with the heater being the only source of heat(minimal at that) hence in winter the vehicles run 24hrs a day!
