Several years ago when in Changi airport I spotted an unattended bag and feeling a bit embarrassed reported it. The authorities
didn't mind a bit however, the police turned up within about a minute questioned me and started to clear the area. Just then
a man turned up to claim said bag. He acted like someone who wondered what all the fuss was about ( he had been away from
it for about 20 minutes.) That lasted about 10 seconds until he realised the police were rather annoyed with him when they all
walked away to an airport room. Never did hear what happened to him but rather him than me
