I am confused why did they operate then?

We are in a pandemic and if people realized they have the virus they will find a way to blame it to others even if they are at fault and obviously, they will blame the casinos or maybe the bars. Despite the level of the casinos, small or not, there will be no exceptions. They should've think this through.

Maybe that is the reason why some casinos, despite the permission for them to operate did not open.
