Many years ago, when my ex wife was still living here, she needed a replacement bank card sending though. The bank promised to send it immediately.
It didn't arrive so she contacted the bank who checked with the post office who said it was delivered and signed for.
Further investigation showed that the card was delivered and signed for but the postie, having got no reply at our house, looked around and saw a man outside one of the neighbouring houses (all the other houses are converted into 5 flats each). He asked the man to sign for the card and then gave it to him.
The postie admitted that he didn't know which house the man was from or who he was so we went door knocking.
We eventually found a neighbour who said their friend called around a couple of weeks earlier when no one was in and the postie gave him a letter to sign for.
Apparently he didn't want to just stick it through a letter box as he saw it was from the bank so he held onto it meaning to knock on when he next came over.
And sure enough he did do. The envelope was intact and the card was still there.
By that time the card had been stopped and a replacement picked up at the bank.
So, an honest neighbour's friend but another stupid postie.
OK, I'm not going to knock posties too much. 90% of the time they are fine, or at least I don't know that they are not, but the rest of the time is just silly.
