Oh, I wasn’t questioning your recall of the interview. I was just wondering about this idea of only carrying out checks on 20 % of fans. The club e Mail also mentions ‘spot checks’ only. That is no change on the pre Plan B situation apart from putting a number on it. The actual rules state that all fans need a Covid passport or LFT and I don’t see anything about 20 %.
It was something the club chose to do previously, now it's a requirement (law) so there is a difference........the 20% is a 'reasonable' check to enforce it (like most laws, 100% checking doesn't really exist)
Given Omicron appears highly transmissible by vaccinated people I'm not sure how effective a vaccine passport is as a control anyway though - actually an LFT would be more use
