Yes, I too am rather intrigued as to how a Young Persons card is apparently being used, in these circumstances?
As I understand it, it is also available for sale to those in full time education and it's perfectly within the rules for them to continue to use it even if they complete their full time education before it expires. Of course, I can't speak for the specific case, Chris, but there are indeed times that the naming of rail tickets causes confusion.
I particularly like the "Anytime" tickets from Melksham ... which on a Monday to Friday are restricted to arrivals and departures between 06:30 and 07:30, and 19:00 and 20:00 - it's a
strange definintion of "anytime" and it strikes me as questionable under the trade descriptions act!
