I witnessed a recent exchange between the SWO (now retired) at Shawbury and a S/Lt Pilot under training.
As he was leaving the coffee shop the SWO notices said officer cycling past and gave a perfect parade ground salute, the young officer, not wanting to offend the SWO thanked him, but in doing so accidentally began cycling the wrong way around the one way system. This was promptly followed by
"That is a one way system..........Sir!"
The officer, now in a bit of a fluff immediately began a 360 which unfortunately in his haste took him onto the grass. Cue an immediate
"GET OFF MY GRASS..............SIR!"
Pure class.
