Hi, I have a similar situation and now it has been brought to my attention I am quite worried. I traveled through london on my oystercard, and was assured by friends that I could use pre-pay to get to romford and that it would have been accepted. rail stations in outer london do, some dont. this didnt. Instead of walking through the gates, like an idiot, I went to an attendant and asked where the oyster scanners were. he said I couldnt use oyster. I offered to pay the fare, and he told me I would have to pay the fine. At the time I was incensed that I would be penalised for a simple mistake - had i gotten off two stations earlier it would have been no problem. I paid whatever I had in my pocket, 80p I think, and waited for my parents to receive the ticket, as their address is more stable than mine. They never recieved anything, so i presumed that they guy had realised what an idiot he was being and dropped the matter. Now however, I am slightly paranoid that my parents have lost the letter and that a problem is building up behind my back.... also, I need to get a CRB check - would this show? thanks,
