When officials asked for the Welsh translation of a road sign, they thought the reply was what they needed.
Unfortunately, the e-mail response to Swansea council said in Welsh: "I am not in the office at the moment. Please send any work to be translated".

"When they’re proofing signs, they should really use someone who speaks Welsh," said journalist Dylan Iorwerth.
