Can I ask some advice ? - is it relevant or should it be Inernational. Daughters friend this pm in Paris on the Metro , encountered a block and showed the wrong (previous) single journey ticket - the proper one was in her bag , and got fined 40 Euros , on the spot despite showing the proper ticket. Obviously a very soft and easy fine , compared to the large numbers of blatent fare dodgers on the system. She paid in cash , has a receipt - does anyone here have an idea (I am sure I can dig it up) , for a back office on this system where a sensible conversation can be had. Thank you.
