I have no problems with ticket formats, I’ve used them all, but when I know what ticket I want I vastly prefer the buying process of asking a human for the ticket I want and being given it. I dislike the journey planner nonsense on ticket machines or online purchases.
It happens that I feel naked going out without a watch or a wallet, so I have never personally had a problem with paper tickets, but the comments here just demonstrate that we’re all different and it’s just that trying to make one solution work for everyone that isn’t good. Currently there’s a choice and that’s fine with me.
Well said, and long may that choice be available.
I prefer to use CCSTs because I live in TfL-land where the barriers aren't set up to accept e-Tickets, I hate having to get my phone out to do things, I have a perfectly usable ticket wallet, and I collect the things anyway. The one thing I do refuse to use is a digital railcard, but that's based on my experience a few years ago when my mother (who prefers e-Tickets) bought a digital Senior Railcard for my grandmother and then the app on her phone stopped working right before a long-distance trip. Obviously I accept that my opinion and my preferred way of doing things is neither the gospel truth nor the way in which everybody must be mandated to do things.
And there has been an occasion when I have found it very useful to use an e-Ticket. I was once travelling from Windsor to Teddington, when the train from Windsor and Eton Riverside was abruptly cancelled due to a fault with the level crossing at Datchet. Immediately I ran up to the castle and leapt aboard a number 8 bus, which I knew would connect with the train at Egham. However, since I had a ticket from Windsor, and Egham is on a different line, my ticket wouldn't let me into the station, and I wasn't sure if ticket acceptance would be in place. With an expected connection time of around three minutes from bus to train, the only thing for it was to buy an e-Ticket on the bus - which let me into the station without the faff of trying to find and use a TVM at an unfamiliar station. Did this experience immediately convert me to e-Tickets? No! But it's nice to know that the option's available, and have the choice and the freedom to use either according to my own wishes, and not according to the whims of fashion or of ticket retailers.
