Gotta go?

In Singapore (and Malaysia for that matter), it is customary to refer to WC's as "the gents" or the ladies", e.g.:
"where's the gents?" or "I must find the ladies"

The first time you hear this it is easy enough to process, but definitely sounds foreign, the same way that "having here, takeaway?" instead of "to stay or to go" sounds a bit odd at first.

But, for the avoidance of future confusion when you've gotta go, here is one useful resource: http://www.wackyarchives.com/featured/toilet-signs-across-the-world.html
