First job I had one screaming down the phone at me to go fetch her papers from our archive and read out some details. So i said I'd need to go ynow... Fetch them as they were in another room and this was a surprise call and she said i couldn't leave the phone. The phone wasn't wireless i couldn't take it with me.

We sat there for a while as she got more and more irate asking me if I'd got them yet but still wouldn't let me leave. When i eventually was allowed to go I spent all of 5 minutes grabbing the forms and when i came back i could hear the screaming from the across the room. Then begun the questioning of why i took so long and demanded an explanation. Then loads of threats about leaving the company and blah blah and how we need to beg for her money blah blah until my boss asked me to hand over the call to him where he told her to fuck off and slammed the phone down lol.

I don't think I've interacted with anyone worse since. Wish i even remembered the name so i can look up if the old fart is dead yet.
