It is a puzzle, with a modern stadium, with modern facilities.
Mind you, I had problems with E-tickets at both Wigan & Hull KR when we were in Super league. Their scanners couldn't read my printed versions. Could be my printer of course, but the stewards, in each instance asked why I hadn't bought my tickets, at the ticket office. One turnstile operator said he'd never seen one before!
As for Fev - come on, you'll be telling me they've got electricity next!
