Imagine requiring this at any large Broadway show -- Lion King, Wicked or the like. Getting 1500+ people screened for three shots and a time stamped test result within 24 hours of the curtain? Imagine the potential contention that might break out at the point of access, when the mutli-vaxxed and masked show up but are refused because they have the wrong test or no test. It's not viable beyond the small 200 seat houses, and remains to be seen how well it works there.
