Walk up to the guard at the door smile n say supermarket, as long as they are not saying the daily pray you can walk in ,you will find many ppl in there.
Hmmmmmmmmmmm I always thought that the lower Hall was always open before 10 am ! Just the 2nd Floor that was not JP
I believe Robinson's Market and their pharmacy along with Jollibee are the only shops open before 10am.
