I totally avoided offline gambling because of this reason and some even set it as part of the rules, you won't win and just quit immediately, you will continue to play intill when all of you that is participating in that gambling has agreed or decided to call it a day. And this usually brings problems, quarrels and fight among the bettors as a result that someone wants to leave after packing other people's money away. It's even more addictive than the online or shop betting because here you're having both fun and in the process trying to earn off it.
I still enjoy offline gambling, but I prefer poker because it's more exciting and entertaining. It's true, as you said, that offline gambling often leads to fights between gamblers because they refuse to accept defeat. Furthermore, if caught, they'll be prosecuted by the police.
But for other forms of gambling, I prefer online because it's more practical and safe. Offline gambling is arguably outdated; all gamblers prefer to play it safe and turn around money in online slot gambling.
The continued emergence of many online casinos certainly indicates that interest in online gambling is growing day by day, leading companies to build a very promising business by establishing their own online gambling sites.
