Has happened a number of times to me and the unofficial story is that the posties are not able to carry the amount of parcels they are being asked to. Personaly I blame internet shopping.

If you postie was just carrying letters there would be no issue but if they are also delivering from Amazon, HMV, etc etc there little bags are going to be bulging.

The person I spoke to hoped that one day the management at The Post Office would admit to the fact and deal with it.

Their only response so far has been to tell postal workers to deliver what they can, leave the rest at the depot and put a red card through our door so we can do the rest.
