Sooo... DID he have a ticket and DID he produce it with an explanation even though it was not a return ticket?

Is the price of a ticket from A to B the same price as a ticket from B to A? If so, why couldn't he have explained the the mistake and offered the A to B ticket as payment in full?

As for him not being given the chance, he had the chance to discuss it when he was approached for his ticket. That's just a fact.

Are these tickets dated?
