One of our pilots lounging in his room in the, then, new portacabins. A knock at the door. It's a Works & Bricks bloke who has come to fix a blockage in another room and would he go along as security. Our hero goes along and sits on the bed to watch the plumber does his stuff.
The plumber undoes both ends of the S trap and carefully, as it is brimming with dirty water, lifts it up and pours it down the sink.
He looks down at his now sodden toecaps, turns to our pilot and says. "I'm sorry about that, it must be the Irish in me."
