I work in commercial refrigeration, still learning, still a lot to learn. I service a large supermarket chain, and am disheartened by the sheer rudeness and lack of manners which SOME of the managers display. How does one deal with the almost tangible animosity displayed by some of these people. it's getting to the stage where things could get ugly pretty quickly the next time one of these bastards tries to treat me like crap. O is it just me?
