Please share stories of the worst work colleagues you've ever had

[BadMoodBoard]

and how you dealt with them

For the past year, the lady I share an office with:

hasn't allowed me to turn the light on (as it gives her a migraine)
eats an egg sandwich most breakfasts
eats a full roast dinner on her desk every lunchtime (fish and chips on Fridays)
Flosses her teeth on her desk
Interrupts all my conversations, butts in, takes over
Asks insidious questions designed to show me who's in charge and sometimes to drop me in it
Will make a song and a dance about her personal plans when I am trying to focus on my work

I hate her

We had a selection of useless and worse than useless managers at the shop I worked in.
There was Silver Simon who accused me of thieving from the till and then left me in the dark for most of the day, before I confronted him after closing as I wanted to know what was going to happen to me. I was innocent, by the way.
He chuckled, claimed it was an error and not his fault. I demanded an apology as he'd called me a thief. He claimed he'd done nothing of the sort (lie) and then gave me the fakest apology I've ever heard.
Then there was Bald Simon. Grade A creepy perve. I can remember a group of us trying to persuade another member of staff to report him as he'd crossed the line from making gross comments to inappropriate touching. She wouldn't, she was too scared of him.
He managed to pretty much upset and annoy everyone in one form or another the whole time he worked there.

hmmwhatatodo she made a reference to what snacks they were afterwards, can't remember what, but they definitely weren't the actual snack yum yums.
