It wouldn’t be anything like 10% of fans.
I think you’d be surprised how many of those “special kind of wankers” exist, though.
People will be in the ground with covid given current infection rates in Brighton. That’s a statistical certainty.
Seems pointless to me.
Had two jabs but that doesn’t mean I don’t currently have / carry covid and don’t need a LFT because I’ve been double jabbed.
LFT is too easy to fake if you just want to go to the game.
Result = check will have minimal impact and there will still be plenty in the ground...
