The notice, which appeared in an London office, asked employees to wrap up their business and leave it on their desk for Brenda to tidy up.
"Please do not use the toilets as there has been a blockage. The plumber will be here first thing tomorrow morning, so for the rest of the day please use the public toilets in the car park." the note read.
Seems logical, right? That's until your read the next instructions...
"In case of emergencies, please wrap your stools in newspaper and leave on your desk.
"Brenda will come round with her trolley and collect them at 5.30pm. Please note that any stools passed out of business hours are your own responsibility and must be disposed of at your own risk."
Chris Shaw received the images from a friend before tweeting them out, writing: "You've got to feel for poor Brenda: 'Hi Brenda, we've got a favour to ask you...'"
His post received hundreds of reactions with many disgusted at the note left while others took the opportunity to use a bit of toilet humour.
I wonder how Brenda's day ended up?
