They'd be insane to demand QR check-ins. There is no way most would happily agree to have their details registered. Writing in your number and 'name' is another thing altogether. Could be a secondary number and fake name, obviously.

I'd imagine they don't ask for proof of vaccination, either? On the flip side, they SAY the girls are fully vaxxed, but how would one know, anyway?

Also, considering they've been running the joint underground this whole time, they probably don't really give a fuck about Covid.
