@fubear: I have observed that efficient access to the beer cooler is essential enough that masked people will get shoulder to shoulder with their fellow man. The winos still maintain 6’.
@voxday: Of course peasants don’t mind crowding. We civilized people prefer to maintain a civilized – and healthy – distance from the unwashed masses. I generally try to maintain social distancing of at least one kilometer.
Then again 1.5 SD is usually sufficient for all practical social distancing purposes.
