I agree at least for cooks, along the same lines as hand washing and hair nets. I’ve actually caught the flu from eating out before, you know those stomach flus that incubate really fast, you can tell. I’ve caught covid a couple times, but who knows how I got that, has a long incubation, no way to narrow it down. Anyway I don’t worry about covid any more than the flu. I almost died from the flu when I was a kid, never got that sick from covid, I mean it was still pretty nasty, but not life threatening.
