Brian, you are correct, although these days rural posties take their
vans home, so I suspect the parcel stayed in the van. Having said that,
the posties are not allowed to keep mail in the van after a shift, but
the chances of anyone checking out in the sticks is remote.

Worth mentioning too that it was a medium parcel, posted first class
Friday, and arrived Saturday morning.

Yes very good, but there are stories of postmen being told that to take
mail home even for a short time could get them the sack. This comes from a
bloke who worked for Royal Mail in Feltham. Big brother is watching you.
