Bump

Today I was travelling on the DLR at Cyprus (going towards Canning Town) and had enough money for my journey. I had completely forgotten to touch in, and lo and behold, a ticket inspector comes round and assigns a £40 penalty! I asked if I could quickly go out and touch in at the next station (all the stations along this bit of the DLR have no barriers) - this would have been like maybe 10 metres away but he outright refused! Is there any chance of an appeal going through? When I was a child (I am a uni student now), something similar happened to me and I was simply allowed to just quickly run out and touch in. It would have been in the same zone so I would have been charged the exact same fare. I am a [very poor] student so £40 is a fortune! Any help would be much appreciated
