In case you didn't realise, here is the deal. I'm particularly aiming this at those commenting along the lines of "long queues" "minimum wage stewards" "not enough QR scanners" "internet will go down" "etc".
I was at the England v Andorra game at Wembley yesterday. That was the NINTH England game I've attended since the end of last season. All nine run under some form of Covid Certification needed for entry.
It's the threat that counts.
If there is an event you really want to go to, and the event organisers say you need Covid Certification to get in, then a lot of people will understandably think - FFS, I don't want to go all the way to X, to see my favourite thing Y, having spent a fortune £Z on the ticket & travel, and not get in.....
So, a lot of people will take that seriously, will sort out their Covid Passport on the NHS App (NOT Track & Trace App), or get the necessary paperwork, or take and report a Lateral Flow Test. That will all reduce (not eliminate) the risk of Covid transmission at the event. And that's job done for the organisers. All achieved by "a statement".
It doesn't fucking matter whether you can implement any checks at the Turnstile. Because you don't need to. It's the Threat Of Checks that works. There might be checks. There might not. There might be random checks. It might be you. You won't know when you buy the tickets, when you commit, when you get in your car, when you get up in the morning, looking forward to your day, looking forward to seeing that thing.
Yesterday, I (happily) had all my passports & paperwork & tests in place as I walked up Wembley Way. Because I didn't want to be turned away at the Turnstile. And, there were stewards checking, but not many, and they didn't check me.
It's the threat that counts.
