Re: Hmmm
"That makes so much sense...as then most working people would be at home to receive "Signed For" deliveries and we wouldn't need to take a piece of card to our local delivery depot a day or two later to collect such items."
If the bulk of the mail that didn't need a signature was delivered at night, the balance could be delivered during the day by fewer postmen. It would also mean that there would be fewer postal vehicles on the road during the day/ faster completion of routes at night.
