At my previous workplace, I had a boss(s) that will shout at you almost anything. At my site, we use walkie talkie as means of communication. Once, I was only ten feet away from him. He yell / shout at me using walkie talkie, from the moment I walked towards him until I reached him and he still going on. And its not even my fault. Mind you, he's not scolding. He's yelling.

and just imagine you had two of them at the same time. TWO. And I survived for two years.
