A woman who was fed up with her coworker using her coffee creamer without asking sought revenge by filling the container with her breast milk.
According to The Sun, the woman who identified herself and "B" waited until the end of the week before she taped a note to the cream.
"Good morning," she wrote, "To whomever has been enjoying my coffee creamer all week... Surprise!!! You've been drinking my breast milk. Hope you've enjoyed - cheers!"
She added, "P.S. It's organic. So no worries."
Since uploading her joke to Reddit, her photo has gotten more than 12,000 likes.
