A white C4 envelope was delivered (that’s the size that holds an A4 piece of paper, the type that needs a ‘large’ stamp under the new* Post Office pricing structure).
Inside was a zero balance invoice from a telecoms company.
Someone had to pay for this pointless print and postage!
I’m just glad it wasn’t me.
* OK, I know it’s not so new, but I still think of it that way.
