Players pay for the fun they are having, just as with any other entertainment business. Casino owner trust that most visitors will lose, after all in the neighborhood . how they finance their business publicize some more. For the sake they construct the casino during this manner that the player will lose all track of time and would concentrate only on his game and the fun he is obtaining. This is why live casinos have no windows and everything is built to attract the player to stay longer and longer thus spending more cash flow.
Speaking from my own experiences I've found smoking as a real problem especially as soon as the casinos become busy. It's a known undeniable fact that most heavy gamblers might be heavy smokers too, perhaps times the smoke becomes unbearable.
