Very interesting. I had a day like that a few weeks ago, shortly before I came down with a very short-lived fever (just about 3-4 hours), and a really bad cough that lasted over 2 weeks. The fever and cough started on Feb 29. Neither my doctor nor I thought it was COVID-19 because there had been no patients in my state yet. We gave no thought to the possibility that I may have been one of the first. By the time I got better, both she and I were no longer 100% sure it wasn't COVID-19. But I'm OK now.
Grocery stores musto do temp checks on everyone entering ... Yes, there will be false positives but this one act keeps other shoppers safe - and keep their employees alive.
As far as shoppers turned away - they get offered a personal shopper to pick up their list - and curb service to deliver groceries to their car. Not perfect but it'll work - and stop government from stepping in with a harsher solution.
I'm NOT thrilled picking up a head of lettuce only to wonder how many hands have picked up before me. Stay safe.
