Casinos are the most affected in this pandemic because social distance is an impediment to providing their services in full and are now limited. The Covid19 can be presented even following the strictest controls because a small error could open the door and infect anyone. We can only take advantage of bets on games that can be carried out with a lot of effort today.
Better they put things in place to make it hard for the error to occur.
I would not encourage the use of enclosed betting centers though. Proper ventilation to allow in fresh air would be fair though. It's unfortunate how cities are built to rely too much on artificial ventilation.
