TBF, at some point they’ve got to test what the results are of this kind of mixing.
I haven’t followed closely, but I don’t think there was a huge fallout from the test club nights they held in Liverpool recently (and that was indoor mixing in a hot and sweaty environment).
So am happy for a bunch of football fans to be the guinea pigs in another test environment.
I get why, on the surface, it’s annoying and looks like a slap in the face. But various scenarios need to be tried and monitored - and I’d rather they did it this way than absolutely everything being a free-for-all at the same time.
