Council could probably do with a test script.

1. Stand back and look at sign.
2. Assert.IsVisible(sign);
3. Assert.IsCorrectlyOrientated(sign);
4. Assert.IsEqual(SignRequested, SignSlungUpByCouncilMuppet);

A spokesman for Oldham Council said "a genuine error was made by staff".

A "genuine error".
"Was made by staff". People that go around putting up the Council's signs are indeed staff of the Coucil.
