Ours comes when he feels like it! Granted I live in a communal block of flats and entry isn't always possible but when I'm here which at the moment is nearly every day he never comes! I wasn't here on Friday and got a letter with the post date of the 9th of January! Various times I've needed things in the post (at the moment waiting for a cheque for £600!) and they either never turn up or turn up six weeks later!
