I too was on this flight this afternoon and must say the crew were indeed fantastic. I believe a lady also hurt a nerve in her arm and the crew were indeed very sympathetic and dealt with it via the utmost professionalism.
However, I must say if you were the chap shouting at the man in the chap in a red hat - who remained calm and collected though out - I think you need to in future take a step back and evaluate how you were coming across. Everyone around us on the air gate could here you shouting “I’m a gold card holder” and “I’m in business class” and frankly whatever the situation was; raising your voice to that level and being that rude to someone is simply uncalled for. The family in front and lady behind all commented how out of order it was.
I apologise if you are not the aforementioned chap, however, given your post I think you were.
Either way, the crew were indeed outstanding and I’m glad they calmed you down.
