I have my doubts. I'm pretty sure it would have been a different crowd against Dover if you had to get tickets in advance. I seem to remember going to Southport (and probably other places - King's Lynn?) and you had to find a ticket office, queue up for a ticket, and then queue up again to get in, and I thought, this is a right hassle. And if you do it by phone and have to spend time giving your details, or do it over the internet and likewise give your details plus spend several minutes turning a computer on, it's still a hassle compared to a couple of seconds to pay on the gate after deciding at a quarter to three that one fancies going. The whole point of non-league football is it's supposed to be free of the hassle of watching big clubs. This is something new in my my time watching Alty (apart from the occasional game, as indicated), and it's the first few games of this new situation. What's the big rush to move on?
As I say, I have no problem with other people doing this, and the Dover match was no problem, but one has to recognise that everyone's situation is different and ideally try and cater for this so far as possible, and I personally will in general not go to away matches if I can't pay on the day, or for that matter if I can't go on standing terraces. My money, my choice.
