I was Duty Engineer on the ramp at Bandar Seri Begawan. Stood at the bottom of the 737 airstairs, waiting for the pax to de-plane when my old boss from Northolt stepped out of the door. We simultaneously pointed at each other and said "What the devil are YOU doing here!" He was seconded to the RBAF as a "Brown-Job" Major instead of being a proper Sqn Ldr. I think he was more surprised than I was.
