Sometimes ticket offices don't offer the cheapest ticket for immediate travel on the journey being made. I myself have been unwittingly sold an Anytime Day Return in the past when an Off-Peak Day Return would have been valid. That's a breach ultimately of a Franchise Agreement, and if the train company doesn't want to resolve it can be dealt with accordingly. What The Telegraph are accusing First Great Western of doing seems to be very different, as they are clear their actions are thought not to break 'the law'. But they do mention that sometimes people get Anytime tickets when Off-Peak ones are valid. Occasionally, this will be because an Anytime is cheaper. On others they might havw become confused because no Off-Peak exists. I can't really tell from reading what's actactually going on and what agenda the paper really wants to push. The only thing I am sure of is that I am as glad as ever I don't buy The Telegraph.
