100%. The fact that we are having a detailed debate about this means that the situation is far from clear at all.
If for any reason I was asked to pay extra for the fare I would have done - though under protest - as I feel the way I booked was perfectly fine - my work would have paid me back any excess I had to shell out after all! But I think this scenario is very, very unlikely to happen.
Like I said the exact same priced fare of £55 is on Scotrail's site for an equivalent journey in March or April and shows as a "Single" with no mention of the word
advance. I can't see how they could argue that fare was somehow not a "proper single". How many people buy "Anytime" fares specifically for a CS journey?!
The fare for the train journey only - no room - in that scenario is astronomical!
