Private Eye often have bon mots about how even the ticket offices don't offer people the cheapest ticket because they can't figure it out.

But when you have to deal with things like (eg, I'm hope I'm remembering this right from someone I know) "EUS-CDF being more expensive than EUS-SOT + SOT-CDF even though both halves are the same train as the EUS-CDF journey", you can see how no-one has a bloody clue.
