I believe they pump it in to filter out all the smoke from all those damn smokers in the casinos, I ve also heard they do put in certain odors into the air that make people want to spend money, it was on the History channel, but then again it may just be the lights and sounds from all those slot machines and the fact there are no windows in casinos so people won t be aware of what time it is.
It is absolutely false.Pumping oxygen into a room full of people who have lit cigarettes would be an absolute disaster.
No, this is absolutely not true. Its urban myth only
What are poeple? If you mean people ... no. They are not allowed to do that. They keep it a bit cooler even in the summer to do that.
Complete urban myth. It would be a huge fire hazard. Air circulation is critical (as you can imagine).
No but they do have alot of Oxygen bars in Vegas. Which does give you more energy. I think it is dumb myself.
NO because of smoking could cause fire hazard. They do use scents though
