I worked for a buttoned-down suit & tie stick-up-their asses American financial institution back in the early 90s and I had this one coworker from Scotland who would curse a blue streak in every meeting / phone call. Anyone else would have been called before HR. He always got away with it. I think mostly because the suits couldn’t parse half of what he was saying. He would call out a lot of bullshit on projects, too. I fucking loved that guy.
