Casinos really don't like the hit and run types and they do everything they can so you continue to play. No windows, no clocks, flashy lifhgts, alcohol, and free food. Keeps people staying at their hotel and continuing to play until they usually end up in the red.
So true, that is the reason why I don't think most of the gamblers will be able to win a huge amount unless you are gambling outside a casino like a lottery or online gambling sites. In my case, I don't usually win a huge amount since all I had is losses after losses, if we will be talking about the long run, in terms of shorter terms, I sometimes won huge amount though it usually ends up in the same place the next day.
