Just to ask...if you successfully bought the tickets at the
Ticketing Booth, and you and your friend goes in, but the
auntie over there refuses
to enter both of you 'cos your friend is only 2 months short of his
21st, what would you do?
Just experienced it yesterday, when I tried to go for a movie @ GV
with my friend.
Sigh.
The Ticketing Side already asked for my IC when buying, and I din
know of the double layered checks, and I had to shell out another 2
bucks for The Island, 'cos it's a friggin' PREVIEW! 
*argh*
