Sleeping in Changi airport

Travelling on the cheap? Need some place to catch some zzzs? There's no better (and cheaper) space than the airport. Now, there's a website that rates airports around the world for sleep friendliness. Folks at Changi would like to know that they are a 2005 Golden Pillow Winner, with praise being heaped for its sauna and shower facilities, free alcohol and the "availability of [...] Tiger Balm", but apparently someone was poked while having forty winks with the "tip of a machine gun" and watch out for the mosquitoes!
