Oh god. I'm self-employed now and work at home, and this sort of thing is partly why.
The IT support who stole loads of computer equipment, wore sexist t-shirts, stank, swore, took endless sickies and then when he was finally sacked, staged a dirty protest on the office doorstep!
The utter loon who was off work with a burn on her stomach because she tried to iron her jumper while wearing it. She was mad in many, many other ways too, too many to list.
The senior manager who never did any work, dressed like a hooker (really - teetering heels, fishnets, micro-mini, birds-nest hair, tonnes of slap), pissed off all her staff yet somehow kept getting promoted by the board. 
If anyone else on here worked there in the 90s, maybe you recognise them!
