What a world we live in! Yes, he could have taken the penalty,
appealed, sued, gone to court and maybe one day got his costs back.

OR, he could have paid the £3.10 extra and then visited the station
that issued the ticket and got his £3.10 back after explaining that
they issued the wrong ticket. Bearing in mind that he wouldn't be
awarded any damages (what is the actual loss beyond £3.10?), this
could be solved in a matter of days - depending on when he is next at
the station.

OR, he could write to One and possibly find they'll give some rail
vouchers as a gesture of goodwill.
