If people's homes are considered to be enclosed, often poorly ventilated areas where the virus is able to spread more easily, why are pubs, enclosed, often poorly ventilated areas themselves, seen as "Covid safe environments" as I've heard them called on many occasions? As someone who spends very little time in pubs these days, I look back to the days when I did and think they would be among the worst places you could go in if you were trying to avoid catching the virus - genuine question, what has been done to pubs to make them so much safer when it comes to the virus than they would have been in the past?
