When I was a copier tech one of my busiest accounts was a reseller of Omega-3 fatty acid supplements (the same damn fish oil you can buy at the drug store) and I sat in on more than my fair share of those meetings. The business practiced positive-negative reinforcement (examples: (hostile call)you did well but you should have offered them a free bottle to stay, or (polite call)you did well but they sounded eager you should have offered them...whatever other bull shit we sell too). I couldn't imagine what it would be like to be one phone call away from being fired by an asshole manager on a power trip. My job as a network admin is to help you, not take your shit because you have a weird ass problem that ghosts in and out of existence or you want to run a Mac in a Windows environment and make it work the same and be pissed that it doesn't. I've hung up on people more than once and I've said I won't take shit from anyone and my boss just nodded and walked away.
