rubbish lah ....
Singapore pools is operated by who ?
you think chaps who really itch to gamble would be deterred by
$100 ?
the $100 was to drive away the local hoi polloi and
maintain an air of exclusivity to the place so that, hopefully,
it'll attract the atas rich who prefers not to rub shoulders with
kopisoh aunties and retiree unkers with their CPF kitties.
but hey .... since entrance is free for all sorts of foreigners
..... 
Ok lar, anyway not an impact for me cos I dont gamble, I only
invest
