All those people in that picture are ignorant about online gambling?
most probably not, just because people know about online gambling doesn't mean they wouldn't play on a casino
Why they are waiting on queue to gamble such a stupid thing and more we are not going to have any fun with such crowded place.
that is like saying, why eat or wait for a queue at a restaurant when you can eat at home? a casino provides an experience that an online casino can't provide that's why
people are there. also, a crowded casino gives an ambience that some people like and also for socialising, and lastly you can't expect these people to be there all the time
and most of them are probably a tourist.
