Another noteworthy detail.

[randomness]

All local calls from phones in the transit and departure areas of Singapore Changi Airport are free. Clearly, this is to make life easier on people who have just arrived and don't have local change or phonecards.

I've been taking great advantage of this by calling everyone I know here. Fortunately, all my friends are night people. So far, everyone I've called has been up and about: one in the supermarket, and two on the metro.

Off to make more phone calls during the rest of my four-hour layover. :)
