You will remember however that officers had to wear long sleeves in the tropics after 6.
You will no doubt recall the tale of the bar in the mess at Tengah where a bunch of guys had been taking full advantage of happy hour. An officious senior officer unwisely pointed out that they should not be wearing shorts in the mess after 6pm, at which point they all removed their shorts and carried on drinking in their shreddies!
Bit of thread drift, but re short sleeves in hospitals, I heard a thing on Radio 4 this morning that hospital workers with beards are less likely to spread infections such as MRSA, norovirus, etc than those who are clean shaven. No idea why this should be, but as a beardie who gets fed up hearing that beards are unhygienic I was quite pleased to hear the item.
Back to RAF shirts now!
