Dear Post Office

Sir: Some months ago, doubtless at some expense, the Post Office informed me that I now had a postcode. Bully for them.

Only they forgot to tell themselves as the telephone bill received today bears no post code at all!

This bears out my suspicion that the whole thing is just a bit of window-dressing to make the Corporation look 'with it,' as it lurches into the computer age. Martin Folkard 67 Beaulieu Avenue, Sydenham, London SE26
