In 65, may father was in conversation with an ex-RN officer and told him I was about to join the RAF. The response was, "Ah, the drinking Service."
Sadly, either because I was easily led or simply an incipient alcoholic, I found that to be the case. Fifty years later, I'm still drinking far more than I should.
Perhaps I was unlucky with the places I was posted, where drinking substantially was the norm?
