in germany its mandatory to wear mask in shop and i saw pictures of signs that that advice people to stay far away from each other. some EU countries like germany are easing up czech republic style as they managed to go through the pandemic quite well by reacting early with lockdown and closing flights from china and border.

in the country im in right now there are no mask rules (sadly), but at least shops have taped queing lines so people hold distance when queing and a plastic screen to shield the casheer from customers breath. at the entrance/exit they hung high % alcohol hand sanitizer for all customers to use.

i saw on hive philipines people sitting with chairs outside the supermarket waiting to be allowed into the supermarket that only allowed limited numbers.
