My wife and I typically have breakfast at the local greasy spoon. Small town. Everybody knows rverybody. Several months ago, they started serving 100% of seats. A month or so ago, health department came and told them to either get separation or be shut down. They went to 50% for a couple weeks and then got some flimsy clear vinyl and put it up between tables. Usless but passed code. Now back to 100%. Today my wife (of 53 years) said "reminds me of when we were kids and practiced getting under our desks in case of nuclear attack". Yep, brilliant woman.
