In Portsmouth, the two major operators (First Hants & Dorset and
Stagecoach) issue zero fare tickets to those travelling on OAP /
Disabled passes, but seemingly without taking into account the origin
or destination of the journey in question. I'm no expert on these
things, but I can only imagine that it must cause nightmares for the
company accountants when billing the council for 'lost' revenue.

Passengers holding multi-journey tickets are not issued with a
separate ticket for each journey, but a button is pressed on the
machine to account for their presence, as are those offering the
return portion of a return ticket. Whether there are separate buttons
for day returns, weekly/monthly/annual seasons, scholars passes etc,
I'm not sure.
