i was stopped on Thursday 13 june, at the bath spa. i never knew i was using 16-17 instead of 16-25. immediately the officer looked into my record and see that my last booking was with 16-17. in summary, when I checked all my bookings i had wrongly used the rail card three times in total. during the interview under caution, I told him it wasn't intentional. he advised I wait for the letter and ensure I reply immediately after i get the letter from the prosecution team. That failure to do so, I might end up in court. I gave him my correct name and address. and he offered me a new free ticket. please someone should advise. infact i was so bold when he was checking the rail card and my ticket because i couldn't imagine myself walking up to him if i am really aware of my ticket to tag in at the gate.... i can't sleep nor eat since then, i am sick.
