You are claiming you don't know how to buy tickets without the use of a booking office, yet you are on here posting on an internet forum that needs to be registered to. It's as easy as doing exactly that to buy a ticket online.
You also you believe to be on the side of vulnerable people, yet you are firmly against anything that helps them protect any money they have this includes the ability to safely store their money instead of withdrawing the whole lot from a girobank. I don't think you are as aware as you think you are how living on the breadline is like, but are quick to determine that others on this forum haven't ever been in the position. Perhaps there are posters here that know far more about it than you, but aren't blinded by some ideological society that should only serve your purposes.
No, I've never said I don't know how to buy tickets without the use of a ticket office - you're making things up I'm afraid. What I said is that I personally (as do some other people) find using a ticket office
preferable for many reasons (including - but not limited to - speed, convenience, and security). My experiences and my preferences are what they are, and make sense for me in my situation; they aren't
wrong if they're different from your preferences. They're right for me, just as your preferences and judgement might be right for you. And note, also, that whether or not you
know how to buy tickets without the use of a ticket office isn't the same thing as whether or not you're
able to buy tickets without the use of a ticket office.
Also, you're confusing storing money and only having an electronic representation of it, with physically having the money. I certainly do know people who would find it extremely difficult to buy a ticket online; and I know people who rely on the use of cash in order to keep within their budget. If you choose to believe that such people can't exist, that's up to you.
And another fiction: I have never claimed that others on this forum don't know what it's like to be on the breadline - some might well do. I do know about
my experience and that of people I actually know; that experience and knowledge is part of what I base my judgements on.
