Alternatively, it could be sold as a benefit of Oyster, as it is with
the Dutch Strippenkaart[1] - say, once you touch in for any bus
journey, you may touch in for free an unlimited number of further times
on different buses[2] within an hour, two hours or whatever. If that
offers a quick return, so be it - I don't think they'd lose a lot from
people doing that.

Plus the scenario when the bus gets terminated short of the destination
advertised on the blinds on the front at the time you boarded! I know
drivers are supposed to issue a transfer ticket, but I'm not sure that
happens often in practice. So if using PAYG Oyster you loose out by
paying for a 2nd ride.
