TLDR;

gomen ask gamuda to revise price.
gamuda reduce couple of underground stations, which shud save gamuda ~5b.
but gamuda only offers ~2b discount, to which gomen reject.
gamuda merajuk coz xdapat songlap.

this reminds me of the story where 2 bothers rob 20m from a bank.
after successful getaway, the younger bro say "lets count the money".
older bro said "20m will take a lot of time to count", just watch the news 2nite & they will tell us how much we hav robbed.
little do they know, during the robbery, the bank manager said, "since the vault is open, lets take 80m & report it as robbed by the 2 robbers".

gamuda is basically the bank manager in the story.
