Reminds me of a friend.
This friend works for a rather well-known parcel post firm with distinctive green lorries. He routinely does 50 hour weeks, and is well known as the hardest and possibly best worker in the depot.
Anyway, it's the Christmas party. He sits down at a table, then finds out that he's accidentally sat on the table where all the managers are. Not just the local guys.. we're talking regional managers, VPs, big head honchoes, that sort of thing.
So anyway, he'd brought his girlfriend with him, and as he's one of the depot's best workers, the depot manager tells him to not bother getting up. Just sit right there, there's a whole crate of champagne on the way.
This was where it all started to go a bit wrong.
See I know this person very well. I have managed to stop this person from being arrested at least once after they started wandering all bloody-handed towards the police shouting things like "WHAT'S WRONG? IT'S JUST A BIT OF BLOOD!" I also know he's opinionated and couldn't give a monkey's left testicle who hears him, especially when intoxicated. So, the story of what happened next is entirely believable, especially since I spent 18 months in that workplace and know exactly what it's like in there.
Well, let's just say that whilst it's one of the busiest depots in the business, it has its problems in how it is run. This friend of mine decides to start getting very vocal about said problems, to the extent of telling the depot manager, now increasingly regretting his decision, to "shut the fuck up, you're fucking useless too."
Everyone got the knife, as it were. Other workers and managers alike, they all got told, and all got put right in their place. Very loudly, and very drunkenly. At one point, bits of pepperoni on the pizza that had been ordered started to be used as frisbees, being thrown at said depot manager alongside comments such as "and here's what I think of your pizza, fatso".
Next day, he wakes up to a phone call from his girlfriend, which went something like "you've got a lot of apologising to do". Strangely though, he kept his job. Not only kept his job, but pretty much made it bullet-proof secure. The big guys up at that table, far from being offended by this drunken tirade, were actually rather impressed by someone with the bottle to tell them in no uncertain terms what they were doing wrong. Also somewhat amused at seeing the depot manager being thoroughly embarrassed.
He still has his job, and now has the solid respect, not only of everyone in that depot, but of some of the biggest people in the company. I believe the term used was "bloody loud mouth.. he's right though."
