One other thing, you mention all the other drivers moaning about getting defects done etc.
One thing you will learn in this industry as you go on, it is infested with depressed miserable sods whom if you paid 'em a grand a week to lie in bed would still winge about it, you get two or three of these and they demoralise an entire depot.
When you go back to work next, take a different view (and some screwdrivers and lube spray to try and sort your window out), try to look at the benefits of the job and avoid the wingers who love nothing more than to convince some young victim to be as anti and belligerent as they, every yard has them, you see them coming across the yard with a black cloud of doom hanging over them, walking depressions with the troubles of the world on their shoulders, and your heart sinks because you know they’re going to moan the same drivel and ■■■■■■■■ they’ve done every time before, learn to avoid them soon as mate and you’ll be a lot happier.
Betcha the same bods the first question they ask you is where you’ve been, where you loaded for, terrified you might have a ‘better’ run than them, just avoid 'em mate and your driving life will improve no end.
