So someone stuck a “don’t waste electricity” on the photocopier and the reply nailed that the maths was massively wrong

@Notinaboyband over on Twitter says, “A while ago energy saving posters went up in the office. Now someone has responded, and I like it very much.”

“A photocopier left on standby overnight wastes enough energy to make 30 cups of tea”

“So leaving the photocopier on, once in sleep mode would not use enough energy to hear half a cuppa…”

This is why you should never patronise engineers.
