[1] This reminds me of the "Not Stansted" tickets that WAGN's
Cambridge ticket office used to issue by default, when because of the
fares rule it was valid via Stansted[2] anyway. So no harm in them
selling the ticket, apart from the fact that passengers (and worse -
some grippers) are liable to take it at face value.

The one we met didn't.

I don't remember that incident, but I do recall explaining it to a
gripper who was featured in a contemporaneous WAGN fly-on-the-wall
documentary; there was plenty of time because they could check everyone
on a Cruiser in about ten minutes, then had the rest of the trip with
nothing to do but chat to passengers. They said they'd never had the
underlying rules explained to them before.

I think I also had a chat with someone selling the tickets at Cambridge
station and it seemed that when they pulled up Cambridge-London on the
screen there were several variants to choose from, but the "Not
Stansted" was the first (and thus default).
