For the semi-random set of interventions I don’t have a perfect explanation. My best guess is that at the start of the pandemic there was a chaotic period where random measures were tried (like plexiglass dividors) at some point, when things crystallized, removing a safety measure already in place was seen as unsafe.
With regards to the international variation, at least within the Western hemisphere, what examples are you thinking of?
