Mrs. F. and I had to travel from Clapham Junction to Twickenham last
night. She has a Z1-3 monthly Travelcard on her Oyster, along with a few
quid of PAYG.

Just to say thanks for all the responses. I wonder what the likelihood is of
being penalised if you are found to not have an OEP when you need one.
Depends on the individual gripper, I suppose.
