If the tech support worked everywhere like the company...
Well, imagine: you buy a straw, and there the straw of some hose is not twisted. You call tech support, leave a request, you are told "wait for a service pack". Then
Going to the factory, you get a service pack: a screw and two hooks. You put it, that is, you put it. Everyone who buys a kamaz after you will get a bag with it "service pack 1". And whoever is lucky and the hood will be twisted, the body will be proudly decorated with the inscription "with an integrated service pack".
