So in your view gambling is business or entertainment,answer honestly.
For the house Gambling is a business while for the player, gambling could either mean business or entertainment(if you are winning of course ) and in some cases both!
-snip-
some come to gamble with the intention of doubling or tripling their money but it does not always come out as they planned.
There is no fun or entertainment in gambling and the end result is a loss, someone has to make some money for the lost time unless you have something else on your mind other than gambling!
No the reason behind why some people enjoy and call gambling entertaining is purely because they do not look for making money in gambling. This behind said, you enjoy the mental challenges and love to take risks. Once willing to loose the money, you focus a lot and there could be a win in the end and not loss always. In case you are in only for monetary gains, you might get hurt by the game of probability.
