When I was there at the beginning of September, I felt like on the street there were too many people NOT wearing masks for my liking (this is on the French side and before they put in the rule that you had to wear a mask outside). But INSIDE? Everywhere I went inside, people were masked. Now granted, I only went to - the hospital, the pharmacy, l'express (both locations), and Super U. And all those locations had clear signs saying no entry without a mask. When Michael from unity picked me up from the airport, he and his team all were wearing masks. I ate at two restaurants that had outdoor seating and all the servers were wearing masks. (so you understand my comfort level, I won't eat out at home yet - I get take out to support our restaurants)

Just my experience, but thought I'd share. I never ventured to the Dutch side (this was when the border was closed so I wasn't allowed to go back and forth), so can't speak to what's happening there.
