Earlier this week Twitter user, Niall shared a poster about saving energy that was hung in his office.
The poster on the left is from Carbon Trust.It was intended to remind everyone in the office that leaving the photocopier on overnight wasted up to 30 cups of tea.
Meanwhile, someone in the office decided to figure out just how many cups of tea would be wasted...
Things got even better when someone tagged Carbon Trust in the 'analysis post'
Twitter seemed to enjoy the exchange quite a bit.
Oh, and this was our favorite rebuttal.
