How many season tickets have we sold? How many of those ST holders would attend the first game they were allowed back?
Pay on the day would be an issue and I cannot see the use of turnstiles or queuing at a window a viable option.
Perhaps buying your match day ticket online and getting a QR code to your smartphone or one you could print off like an airline ticket. Main gates, open 2m spaced queue, steward scans your ticket/phone.
There are lots of ways around it. But as we are still in T3 we can watch what the likes of Carlisle, Exeter, Crawley etc are doing before finalising our own system.
