you have to ask though, if this OK for this game & doesn't breach any rules, why couldn't it have been done for previous games?
I guess it's logistically pretty tricky. Whilst perfectly legal, bars and clubs can open so as long as that is what it is then great, but who would have thought about opening up the bars at the stadium for games without opening the stadium itself? Also up to a couple of weeks ago we were gradually getting less and less restricted, so why would anyone be planning for a semi-final we weren't likely to be in, in a lockdown situation that didn't exist at the time?
My guess is that lost of people are running round like headless chickens making sure this works as it should and doesn't cause a problem for the club. I'd also guess it won't make them a penny, but is done purely because the guys at Wasps really want fans to be part of what is happening...
