You know why, they have been exposed to this polluted poor quality of air on a regular basis because when you see them- they appear like short of breath or dyspneic due to all the second hand and third hand smoke they have been exposed to for a long time. It is a pity to all the senior citizen and elderly people who regularly come here. At first when the casino is not that full of people you can tolerate it but during peak hours or at night or near midnight when all the smoke has accumulated you inhale all the smoke and you basically feel the congestion and stuffiness of the poor quality of air you are breathing. This casino is the most poorly ventilated casino in California.
