Entertainment might be different for everyone and it is important to know what is your entertainment and what are you planning to do to be entertained. I don’t think it’s always going to be straightforward because we are all different and it is in terms of what we want really.
I hardly believe that gambling has an entertainment side without a doubt. Is a good way to have a good time.
Definitely it has. According to wiki "Entertainment is a form of activity that amongst other things
"gives pleasure and delight". When I visit local casino I may meet my friends there, may have a drink, may listen to jazz combo, may win at length, sure eventually. Some of these gives me a pleasure while others brings me delight. Thus I kinda see the gambling as an entertainment.
