Singapore is practically crusiy wherever you go, you just have to be more observant and watch for the tell-tale eye-contacts.
Singaporeans are generally shy or proud when it comes to making the first approach. You can spend hours looking back and forth at each other without anyone willing to make the first move - a behavior we usually termed "AC" which means "act class" (See below).
Be daring, and rid the fear of rejection, then you may be in for a whale of al time!
