Courier
I love couriers in this country.
CRN is in one of the most conspicuous buildings in Broadwick Street, being a huge red brick construction on the corner - but one courier today managed to deliver a very important package to not only the wrong building, but the wrong STREET as well.
I then got a very impatient phone call from this guy who couldn't understand why I hadn't received the package and why I didn't recognise the person who had signed for it.
That could be because they work for a completely different company and have never heard of me before.
Luckily it was sorted out eventually after a few increasingly frantic phone calls.
I think he needs to learn how to read a street map - or generally I find looking at street signs tends to help.
