All official road signs in Wales are bilingual, so the local authority e-mailed its in-house translation service for the Welsh version of: "No entry for heavy goods vehicles. Residential site only". The reply duly came back and officials set the wheels in motion to create the large sign in both languages.
Unfortunately, the e-mail response to Swansea council said in Welsh: "I am not in the office at the moment. Send any work to be translated". So that was what went up under the English version which barred lorries from a road near a supermarket.
The notice went up and all seemed well - until Welsh speakers began pointing out the embarrassing error.
