He shouts at the production staff and ignores junior staff or those he seems insignificant. He regularly yells at camera ops, floor managers, runners, assistants etc and is utterly up his own backside and thoroughly unpleasant
i think the term 'shouts' and 'yells' have lost all meaning though. At my job over the years I've regularly heard colleagues say other colleagues and bosses 'shouted' at the them when they didn't. They were just reprimanded, their incompetence was pointed out or were asked to do something.
I worked in schools too and kids always say teachers shouted at them when they didn't.I've even heard parents say teachers did it in parents evening when again there was 0 shouting, the parents were just being told something they didn't want to hear.
In my private life I see others do it. My ex used to always say it to me or others when he was simply challenged on something. He'd be like ''stop shouting at me'' to try and deflect when I/another person was speaking to hi in a normal voice but he didn't like what he was hearing. My parents and sister do this too when they get challenged...
Bottom line is people use the terms ''shouting/yelled/screamed in my face...'' as a means to make the other person sound in the wrong when their own behaviour was being called out. Often it's pure gaslighting going on and to villainise the other person.
