I know for a fact that AJ was sent a letter circa 2-3 years ago from the then planning manager detailing explicitly how MOB was F**king the job up and also the way he treated his staff.
the letter made it to AJ he spoke to MOB, mob then came down on manager like a ton of bricks and said "no more letters to AJ...EVER"(shortened version expletives removed)
way i see it AJ knew...he didnt care as long as the job got done and he made money, he didnt care how.
