I once went to a night club in which smoking was allowed, never again...
I guess these casinos are more ventilated, but still... The smell of smoke is just so bad and so persistent. I would not like to wash my cloths every time I go to a place like that, so I would just avoid them.
There is a study conducted (can't remember where) that the person is more prone in enclosed areas so if a carrier went to an enclosed area where it is not ventilated then the people out there are more prone to the virus and it can be transferred airborne there.
The ventilation of the casino you went would help the reduction of spreading of virus and instead of going there, better not to go to have no risk

.
local casinos in lousuina are open too, but mask are mandated and it smells like cleanin solution lol
Well, even they are the epicenter of the virus the country still opened some of the casinos but at least there are protocols to be followed then maybe it is still good :X.
