Thing I don't get is what did they need so many for? You can't cash
them in (unless theres some black market for them) so unless they were

Yeah they're valid only for 13 months from the date of issue. We see
quite regularly people buying season tickets with a number of these
vouchers, and no way were they delayed by 15 minutes all those times
in a year! Sometimes they have up to 15 from the same date!

They are transferable though, so potentially they could be sold on for
less than face value, making a profit for the dodgy folks.
