Last night I was travelling from London Waterloo - Exeter St Davids on SWT when at Honiton my plans changed and I had to go forward to Tiverton Parkway. I found the guard on the train and asked for the extra ticket but his machine was broken. I arrived into EXD at 2041 2 minutes early, and there was a train to TVP at 2045 and 2050. This is where it gets confusing for me, I went over to catch the 2045 service which isn't an official connection and I waited in the vestibule between Coach A and B for the guard. This was an HST and with not too long before atations I actively sought him out with card in hand. However he refused to give me a railcard discount and said that he should be giving me a penalty (didn't think TMs could do that?) Anyway, He charged me £5.40 for the Off Peak Day Single. Which I believe should have been £3.30. So Was he right or was I overcharged?
