Some of you need to grow some thicker skin and deal with a controller raising his voice at you. I'm pretty sure that most of you current and former instructors and captains have used less than professional language with a student or FO who is making the same mistakes over and over. I for one can't understand why they don't yell at us more considering how many times we goof a readback or straight up miss a call. And if this controller was as short and "unprofessional" as some of you think, I doubt he would have handled it as camly and efficiently as he did. If fact it sounds like the United crew was more irritated than anyone.
