When my wife got back from picking up our food order last weekend she said all the restaurant employees were wearing masks but most of the customers were not. I am concerned that many people seem to be interpreting "gradual reopening" as "the pandemic is over". It's not, not by a long shot.I'd be a little concerned as well. Of course you have no idea what was going on "back office", but from what you saw, were they all wearing masks?
Yes, the incubation period can be as long as two weeks, but do you know the modal number? Guess I've never heard it.
