Why is it we are still living in the dark ages regarding ticketing?

It’s a nightmare trying to get tickets, the office shuts at 4pm which is not helpful.
I can buy tickets online to championship side barrow and keep them on my phone as e-tickets but to go to superleague Leeds I have to have them posted out by snail mail. Here’s hoping they arrive on time eh!!!!

(We weren’t sure if we could make Thursday as hubby is on a job in Scotland and wasn’t sure exactly how long it would take till he got there today)

I just don’t understand why e-tickets arent used- Ticketmaster do it for everything else!!!
Another example of being in the dark ages.
