OK. And with planning, how would it have gone down?
I'm not going to go into possible details of what could have been done, but a strong unequivocal stance that 770 would be shut down
absolutely and for EVERYONE as of טו אלול if there was any hint of non-compliance might have sent a strong message.
Unfortunately, the only powerful message coming from 770 is that if you don't make sure to pay Kratz for your locker in what he considers a timely manner, you will lose it.
Requiring proof of antibodies/recovery from COVID-19
along with a HIPAA waiver (or foreign equivalent) that will allow verification of any documentation submitted, and actually doing such verification might have helped. 1414 implemented something along those lines (though I don't think they went as far as the waiver, and they probably should at this point).
Another possibility is actually investing in rapid COVID-19 testing.
As I said, there are many options that might be available to 770 (at a cost) that aren't available as a more widespread policy. Any and all of those should have been considered.
