I got fined for not having a ticket on the train last month.
However I had a good excuse so I appealed. Today I got a letter telling me they had cancelled my penalty and would be sending me a cheque. The tight gits have taken the price of a single fare out of it though! I did even buy a full Zone 1-4 travel card after I got fined anyway so they didn't need to charge me for that!
Still it's satisfying to get some money out of them. The ticket inspector guy was a right git. Quite tempted to take a trip down to London (with a ticket of course) so I can tell him my appeal was successful! ;)
