Thanks Bota. Yes, during meeting,he keep quiet. I do the
talking. He very smart type. I do the dirty works lah. While
he keep quiet .
Recently my manager asked me "Does het know how to do the job?"
I replied "No, he dare not ask you fearing you know about it"
My manager look at me shell shock.
And he loves to put words in my mouth when he talk to other
colleagues.
come one he this type cannot get job outside 1. have to stay in
this company and gossip tok rot everyday. like my example. never
tok to supplier before supplier come hide. let supplier screw him
good good then he know. reject reject reject what? the other one is
his comondity also cannot move, stuck still got cheek to idea my
comodity. then his stupid suggestion let supplier replace one
critical part once in 3 months die like that. i must change it,
even if it means losing my job. do i need a job anyway? 
my gambit is dispensible wghile he cannot afford to not even
work for 1 day.
