I've just remembered who Marsh reminds me of. There was a sergeant in the SWO's office at Bruggen when I arrived in 61 who was always pushing people around, above all when he was O/Sgt or when they went into the SWO's office for any reason. He always arrived aggressively in the Malcolm Club at exactly closing time and would not allow anyone to finish his drink, he would have to leave, NOW! (Pointless, as there was an open until late German Hof opposite the main gate, another just down the road, and the USAF always welcomed us in their bar.) Sergeant P@ll@s left the much rougher NAAFI bar, where the RSigs drank, to the O/Cpl. The all-ranks Golf Club Bar he left well alone, in case he called a suited SAC "sir" by mistake I wouldn't wonder.
Change of SWO, change of times. A new SWO arrived, who had been an Air Engineer, a decent, friendly bloke, somewhat rotund, whose main interest was golf. SAC Bloggs arrived by appointment to see Mr Swobbly about a golfing matter. P@ll@s pulled his usual stunt of standing up and shouting at Bloggs for no particular reason. Swobbly then stood up, visibly angry, and told P@ll@s: "Sit down and be quiet! He's come to see me not you!" Strange to relate, P@ll@s didn't last much longer in the SWO's office.
