In Capital I don't see anybody not wearing a mask.
If you come to Palermo Soho at night, most people hanging out at cafes/restaurants/beer places do not wear a mask (indoor or outdoor).
In the daylight, I often seen people with no mask or with the mask under their chin. The police doesn't tell them anything, and sometimes even policemen take it off (also in group).
In this hot weather, if I have to walk a lot and it is very hot, I slip the mask, as well, and put it back if I have to come close to someone. Of course, walking on the street early in the morning means I can go 3 blocks without a mask because there is nobody out, but at 11 AM it is impossible to take it off because the population is just too dense.
When I am sitting at an outdoor table having a coffee or a pizza, there is people eating next to me less than 2 meters away and people walking on the sidewalk next to me. I have relaxed a little bit because it is bloody hot.
We spent a few days in San Miguel del Monte, and most people were wearing a mask in town, too. A shop owner commented there have been many cases in the town.
