I remember having this kind of experience when I was still young. The ones who actually forced us to keep on playing are not just gambling addicts but gangsters, too. We cannot walk away with the winning money because they will just keep on playing, and they will use any means necessary just to keep us from the same space. We cannot even take a pee because they think we will run away.
They are using their watch and keys to their motorcycles as bets which made us more worried that we cannot get away anymore. Luckily, we are playing outside and some friends came over to check on us so we got away.
There are indeed people who would use their power over the weak. And I believe, up until now, it is still happening. It is just that because of social media that we have today, such situations are diminishing because it is too easy to get a snapshot from your smartphone and report to the authorities. Times are changing and so the manner of extortion is also changing.
