I remember snapping at work once, due to an idiotic assistant manager, and it being a sunday in store in the run up to xmas, and a ton of people calling in sick.
He did just about everything to stop us actually selling stuff, continually calling one of the two people in away from the tills to do pointless tidying or display work, we constantly protested that perhaps we should be serving customers and selling things, 'you know, as we work in a SHOP!' but it was to no avail.
Fortunately as the queues got greater, one of the regular customers went over to him and said something along the lines 'oi mate, why don't you quit what you're doing and try helping your guys deal with the queues?' and he seemed to actually remember what shops are supposed to do for a while.
After telling us that we're not getting lunch breaks, cos there aren't enough staff, and both of us telling him we're going home and he can run the place on his own, we got our breaks, but both ran out one at a time and covered each other, taking about 20 mins instead of the hour, because despite him we actually cared about our store and the customers, and then closing time came around, and time to prepare for the new releases of Monday morning before we could go home.
At this point he said a multitude of borderline neanderthal things involving our lack of dedication, work ethic and other shit, and I went silent and walked away.
He then found me banging my head against a wall going 'make him go away, make it stop make it stop', and said nothing, just walked away.
We get everything done, staying over time, despite him, as we don't want to make monday morning shitty for our mates.
I come in Monday morning and the area manager's in, turns out to call me into a disciplinary meeting for 'affecting staff morale'.
Trouble was, I was so genuinely shocked at how that shit had twisted everything that I couldn't speak, I just say there mouth open while they read all these fabricated charges.
I then walked away with a black mark on my record and the twat probably got a bonus for being even more of a c*** that expected.
I'd like to say it had a happy ending, but as far as I know he wasn't hit by a car.
