Passing a fake fiver to a bank or slipping a ballotis one thing, contracting or bringing home to my loved ones a disease you're carrying because you actively don't know or don't care about and breathing on me for two hours is another. Not to mention to the house staff of these theatres that have to breathe in audience air eight times a week.
People are literally forging vaccine cards to get on planes. It's small, but it's more than anecdotal,but it's a fact, and it's totally fine for people to have concerns. Not saying throw the baby out with the bathwater, but those concerns are legitimate."
Bringing something home to someone who cannot be vaccinated is, of course, a legitimate concern, even if it is statistically remote. Wearing a mask makes it that much more remote, to the point of virtually nil. (And this applies to house staff which will be fully vaccinated as well.)
Regarding getting on a plane with a fake card, since no vaccination is required domestically, this would seem pretty weird to me and the notion of doing so internationally is fraught with risk that, while I don't doubt someone has tried, seems incredibly dumb since you could end up unable to return. For instance, checking for fake serial numbers is pretty easy to do and while it would not be likely at a theatre, it certainly would be when you are passing through an immigration gauntlet. I think the bottom line remains that all of these things are little more than theoretically possible as a source of concern.
