Sorry, I can only see very, _very_ exceptional circumstances,
in which paying full fare to go from the surface at Euston to
the surface at MC would be a good idea.
For example, if I needed to go somewhere North of MC, and
there was a violent riot taking place in Eversholt street, I
might consider it.
And if there was a non-violent riot?
