Aye, it's extremely frustrating, because how much you enjoy a job, vastly depends on the people that you work with. And sure, there's always a good few that you get on great with (unless plot twist: you're the cunt), but all it takes is one utter Piers Morgon or one skeletor-esque character, to completely ruin it.
One of the people I used to work with was a proper coke head and he would accused me of brain-washing him and even reading his mind. I tried using my powers on a waitress and brain-washed her into going out with me, but 5 days into it and she, along with my beloved, signed VHS of "BioDome" were gone.
But I digress, the point still remains. If you are in very close perceimaty to this person, then I woul try and have words with management if the problem is really that bad. If he is qute far down the office/workdplace, then you could always fill his coffee/tea/special brew with tiny broken shards of glass. Personally, I don't agree with murder, so I would go with the former.
Edit - And heyooo Shambles

. I would bow out of respect,, but my various ailments prevent me from doing so. Instead, I shall give you a practically empty liter-fluid canister, out of respect.
