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.
I think that conditions changed after thiis pandemic happened. I.mean not just in casinos and night clubs but elswhere in all indoor spaces. They need to obey much harsher hygene and health measures and that is for good of all of us. Although I can understand that for long time sone people will stll avoid places like casinos.
