twice,both bad experience
First in 1990,part of NPCC march in continent.Never forget it.Practice so hard for all the rehersal,everything done,actual day itself was picked out to be a reserve.Ended up our group of reserve went to the present esplanade bayside,sit down sing songs...........
then food was only one tao sa bun and one package of soft drink for one full day.
Second time was duing army days 97 or 98 going in to form some stupid display,weekend all kena burned and in the end the supposed to be given back off in lieu all kena eaten away too

But this time food a bit better,got KFC.
