I've only been in the industry for four years, but I've enjoyed every moment of it (I probably haven't said thad that everyday, but it's true). Ok you do find some crew members that you just cannot get away with, it might be a clash of personalities. At he end of the day we have to grin and bear it. If you asked them to do your job, they would probably say no, because A. They dont know your job, and B. They probably do respect you for doing it, but do not show you that.
If they are having a bad day because of fog somewhere, they are probably thinking at least Ops will be pulling their hair out aswell, and vice-versa.
I've dropped some right bollocks in my time, one fairly recently. An aircraft diverted to Lille, so I put a flight-plan in departing from Lille. I then got a call off the crew to say there was no flight plan, here's me thinkg there definitely is, until I looked at the departure station....it wasn't Lille. I just appologised and that was the end of it, the Captains word were "Mistakes happen to everyone".
Keep smiling
