the chap had pre downloaded all 4 tickets .... it was the very poor wifi signal that struggled to connect, and then subsequently the turnstile operators device was also struggling with wifi ... result 5 min or so delay at the turnstile,
anyone can download in advance as much as they like, however if , when they go to access said downloads the wifi signal is poor/ non exsitant / sporadic attempting to access those downloads is problematic at best, and impossible at worst
Boosting/ increasing the wifi signal at the breeze block is an absolute must IMP
