Hypothetically, what if I can't find my ticket when the inspectors come for whatever reason (battery died for eticket, or maybe kept in overhead suitcase and didn't check there or dropped under the seat etc) and I get a PF. But I then find it when am still on the train and journey is ongoing? Does the PF get cancelled?
What if I only manage to find it once I am home?
