actually it's human nature lor.. like a man sees a woman
normal one.. bor chap..
but he sees a woman being wooed by another guy, he will try to
win her over (gain possession of the woman, like boy-girl
relationship),means i win liao feeling..
but time goes on, the excitement gone liao, he will "drop/dun
bother" this one and go find another one to fight over again..and
claim his own..
something like that?? 
lol
but tis one is tat they didn't want to bother to 'woo' or rather
promote it to others... so when others 'woo' it, made it to become
famous, now they want to grab e credit lor
I think it isn't just food.. Even containers port handling, I
bet they must be knocking themselves now. Back then they didn't jio
MSC over cos it was a small fish tat time, you see how big they're
now
