a few pennies x millions of sbc.. not hard to, not think g.m. would require that...
it was more likely g.m. had another surplier that walked in and said they could surply them for x amont less.. and g.m. told mellings if they wanted to keep the contract. they'd need to meet the oursourced surplier..
thats more of a believable been counter story..
