What are chances your vendor bitches about someone else's code?

I met my ex-vendor on the train, he was complaining about the code developed by the atas vendor. They hardcoded a lot of values and he had to fix their bugs even though he was only contracted to enhance the program.

We worked together for another similar program, and I decided to redevelop the whole thing because the one developed by the atas vendor wasn't scalable. So he was comparing what we did good with what atas did bad. I thought it was quite odd for us to be bitching about the atas vendor's code.

P.S: atas is Singlish for "high-class"
