Or have you played in this kind of underground gambling den before?
In our place in the province, there is a gambling lottery game that is happening everyday. Its besides the Official Lottery that we used to heard. This one is like a small known gambling but everybody knows its prohibited. The only reason its being conducted cause the owner od that one is influential person or probably got some ties in the Government there. Well its not allowed but due to the closeness to the Government (Bribe for sure) its being allowed. What a nonsense undergound event.
Most of those places if you have influence especially if you can bribe politicians of police officials you can facilatate illegal business like this, as even people/gamblers knows about it they will continue to encourage those kind of underground illegal gambling, as losng as they can please/fill the needs for gambling it won't matter what they wanted is to gamble and try some luck to make money..though most of the time they lose it.
