OK, stupid I hear you cry. Send it registered or recorded... you are right. However. The times post has got lost in the post must be microscopic. So.... last week my wife sends £70 to our grandson within his birthday card. It never arrived. Since then we've heard similar tales of non-delivery when cash has been involved. Is all this purely co-incidental or is there a way of 'flagging' if there's money in a sealed envelope. Or.... the fact that there is an obvious large amount of post on a particular day suggest birthdays and possible raw dosh within. Is this just unlucky or is there something more sinister? All the 'posties' I know are great guys/girls, so we're in a quandary. Any thoughts or any other similar stories?
