Singapore retail market is dead. Walk into any of the 'shopping centre', more than 50% is F&B and the rest the same chain with the same display you can find just next door. Beside lunch an dinning hours, no reason to go there. Of course, the Ah Pek and Ah Soh get air con enjoyment hahaha
Any available space, they put kiosks or add another unit, you will never find an area to rest or wait. So, you just have to walk and walk. If you are not buying, please leave that is their message.
Of course, sooner, you will be 'body rubbing' if you wish to enter one of these shopping centre.
