Re: Optional, Anonymous and Effective? Choose Two. At Most.
Fair enough - if you've been close enough to someone with Covid in the last 5 days that you could have caught it (and you haven't had and recovered from it yourself), then I don't want you in my restaurant.
Life isn't going to return to normal until we have a vaccine, a cure, or incredibly cheap and instantly-working test for both whether a person has it and whether they have had it. This is something a lot of people need to accept, but may not have even realised yet.
In the meantime, tracking who might have it is the only weapon we have in the toolbox (other than hiding in the toolbox)
