Hiya PTC
God love ya, but your post again just really goes to reitterate the fact that you need to get a thicker skin. You've joined (again) BA at an incredibly difficult and tense time. The atmosphere onboard the jet and down route is going to be unpleasant on occasion and it'll absolutely consume you if you let it.
I used to let it, so I'm speaking from experience. Now I'm happy to get on, do my job and not take sh*t from anyone.
