I had all three shifts doing the covid screening in the General Campervan field (I'll get an arena shift one day, surely) and it never really got that busy. We ended up having to Hotspot people a few times to get them on the NHS app. Only had a couple of awkward customers, one a very angry woman who was pissed off she couldn't use her card as proof. Fair enough, it's about as secure as showing a negative LFT text message but they were told before (and told to screenshot the app because of the shit mobile coverage). She was genuinely furious, the kind of angry that could knock a less confident steward, but the guy she shouted at has done it for ages so wasn't bothered. "I have my card, I have cancer(!?) and I just want to get in to this fucking festival". I'm working Wilderness next which isn't a test event but is using the same system. And I'm told the mobile coverage is even worse.
The second was an old fella who'd actually been through the day before but came back to tell me that the whole thing was a scam as no one was actually checking anyone's covid status as he wasn't checked. It was all a conspiracy by the government to make it look like things were all OK. As a lowly volunteer steward (not even a supervisor this time) government conspiracies are a little above my paygrade. But then I would say that wouldn't I? He was harmless enough, and to be honest entertained me for a few minutes during a fairly dull shift. I pointed out that was literally why we were there, and offered to let him stay and watch us check people as they came through, but he seemed less bothered by this point. Especially when his wife pointed out she had been checked! So if he'd just mentioned it to her he could have saved himself the time!
