Hey, Captain Smiffy; it is indeed a funny old game! I recall flying a Bulldog (XX549) from Woodvale to Blackpool back in the 80s. We were given a similar instruction - to report right base for a normally left-hand circuit. Now I was just a stude back then, but when my QFI (Uncle Rod) asked me what ATC meant, I managed to work it out! 🤔.
