Masters certainly were 'real' WOs! One of our M Eng was on some course or other at some pongo establishment and went into the bar for a pre-dinner drink....
He was told that he couldn't be served until the CSM was in the bar. This didn't go down too well with a rather thirsty 'Caring Ken, the airman's friend', who told the barman that he outranked the WO2 CSM and would like a beer, please. So the barman obliged...
Enter the CSM, who was clearly perplexed by this breach of pongo protocol. But on meeting Ken, they discovered that each had the same militaristic view of life and they got on very well with each other, went into dinner and propped up the bar later until closing time!
