Whilst we're on the subject of boundary zone tickets, I occasionally need
to go to Chelmsford. At Liverpool Street I usually ask for a BZ2 to
Chelmsford ticket but my request usually gets refused as I'm told that
there is no stop in Z2 from Liverpool Street towards Stratford. I seem to
recall reading that there's no requirement for there to be a stop for a BZ
tickets (unlike named stations), but have never felt like arguing the toss
for such a small amount. Who is right in this case?

Aren't BZ tickets only available in one direction (eg BZ to Chelmsford, or
Chelmsford to BZ) I can't remember which way round it is.

They're only available *from* the zones but they are available as returns,
in which case the return 'half' would show (in this case) Chelmsford to BZ2.
