Not personal, but I observed it and heard the RT exchange. In 1987 at Leeds Bradford, ATC instructed the crew of a JAT Boeing 727 to turn right on to the taxiway. They started to turn left. The Tower controller rectified the situation with repeated plain English at some volume: "Yugair 2759, RIGHT, RIGHT, RIGHT". They got the message.
Around the same time, the crew of a Hispania 737 bound for Palma made a complete pig's ear of an ATC clearance readback (this was years before Leeds Bradford embraced SIDs). The Tower controller very patiently said something like, 'Hispania XXXX, negative, let's start again, shall we ?' Second time was the charm.
