Back in the days when we had an air force, at RAF Brawdy there were very few OMQs on base. So when it came to the question of Christmas Day SDO, the Stn Cdr said that rather than ask for volunteers, or draw names out of a hat, he would nominate someone and there were to be no arguments.
Which he duly did.
Who did he nominate?
Himself. A fine example of leadership and much appreciated by everyone.
