Fact number 4 is so disgusting that I have no desire to even discuss this topic. I feel a mixture of pity and disgust for any addicts and this is not the worst thing they are capable of. Such people need serious medical care.
I don't know if this is still happening right now but I agree that it's really disgusting and in physical casinos they have a lot of comfort room where you can take a break and pee, Well, I guess it's too much addiction and if they continue gamble this way their health will surely compromise and they will experience some health problem. I haven't witness this kind of fun facts aside from a gambler making a scene in the casinos, which I think is very normal especially if you lose your control.
