But if they don't take care of the health of their gamblers seriously, it's a loss for them. Thus, they also have to follow it because of the local government rules and that's the reason in the first place why they're back at it again.
Taking health is not difficult, but most people are not aware of that, and only in this Covid-19, people now become aware of health. In everywhere, public areas, hand sanitizers, and water to wash people's hands are available, and they suggested to clean their hand before entering to one place. I believe that should be done in the casino, so their customer and employees will always remind each other about clean.
If they can do that, yes, the casino will always allow reopening their business, and perhaps, if that succeeds to be applied in one casino, the other casino should follow if they don't want to get a problem in the future.
The sanitation has always been part of their operations and disinfecting will be part of the new norm so, expect that most casinos that will be opening which will conduct poker tournaments or any kind of tournaments in their jurisdiction will apply it.
