This thread has really made me want to go back to work - i live for this shit! It's the only good part of office work.
I have so many stories of when i have been left open mouthed and blinking at a colleagues outrageous behaviour.
My particular favourites (both public sector/charity jobs).
Milk - we had i pint a day paid for by work. Which for the amount of people in the office covered a splash for a cup of tea/coffee for us. But one colleague used to make porridge with half a pint and a milky coffee by heating a whole mug of milk then putting the coffee in. She would get in early like me, i would make a tea and she would then use the rest. By the time the others came in there was none. If someone brought their own in (me) she would just do the same. When i said something she would tinkly laugh as if i was joking and say 'i think (insert employers name) can cover my breakfast after all the work we do for such shit wages' and i would try to point out she wasn't taking it from them but from everyone else who then couldn't have any tea. Blank look.
THE bowl - My Nan had bought me a bowl, plate and mug set when i started my first job after uni. I kept it in my drawer at work and one colleague kept helping herself to it out of my drawer. I would only know when it wasn't there and i would go looking round the office and find it dirty on her desk. She wouldn't wash it up but say 'oh yeah i've finished with THE bowl, you can take it now'. This would piss me off as she always referred to it as THE bowl as if it was communal property. Even when i told her repeatedly that it was MINE and was in MY desk.
One day at about lunch time she came into my office a bit annoyed and the conversation went:
Twat 'Do you have ANOTHER bowl?'
Me
'no, just the one i always have...'
Twat [hufff] 'well i need to eat my soup and i've just dropped THE bowl on the floor and it's smashed'
Me 'What?! you've broken MY bowl?'
Twat [looking like i am being really dim] 'YESSSSSS, that's what i said and now i don't have anything to have my soup in, do you know where another bowl is anywhere?'
Me
'So my bowl is completely broken?'
Twat [Really annoyed that i'm not getting the main issue of the situation] 'I've already told you that! i'm going to have to go to the canteen and borrow one now' .
Me
I went into the kitchen to find my broken bowl still in pieces on the floor.
And don't even get me started on the boss who gave my bottle of nice white wine to a client then replaced it with a bottle of Mead
