Lansai lah knn many people, including male sinkies will sign up saf when they doesn't know what to do and have no directions. After their contract terms most of them also moved out of saf.
It is just a temporary shelter, nothing new. Those that continue to stay on are the losers of losers that still doesn't know what to do outside of saf.
I know at least 10 uniformed chiobu from rsn during my service. They are much more chio than her in rsn number 3. Rsn has much more chiobu than rsaf All of them also moved out mah.
