well, that was the first sentence i heard from an army personnel when i first enlisted, was sitting in tekong auditorium chilling when someone was shaking his leg, then one of the sergeants come over and told him off (in that manner) lol.
anyway, they use that and more in army. if you have a civilised commander they talk really nicely though. there are always exceptions everywhere.
but i still dont understand why drinking on stage is disallowed in singapore. maybe make the shows nc-16 or smth if they scared kids learn from their idols.
