No reason for anyone shouting at you, all it does is brings to attention how close the loud mouth’s knuckles are to scraping the ground.
The only thing i’d change about what you are doing is:
once connected up put the clip on then and shine a torch up the 5th wheel’s bum to check the bar is across, so long as the tractor unit park brake is applied that trailer isn’t going anywhere.
Ignoring the trailer park brake for the moment, the clip is the first thing i put on and the very last thing i remove just before pulling the handle when dropping a trailer.
Other than that i too fit the airlines first and go around anti clockwise, whether dropping or picking up, its when you change a routine that things go pear shaped.
