this fails to consider that if an employee of the store tests positive that has an implication for the store itself as well as all the food and products being sold to the public.
If you want to argue for less extreme measures, I will probably support them.
I think everyone should be doing this, there's no way to track possible infection through the entire supply chain but since the virus dies after some time, inner packages are probably safe if they've been untouched for a while.
