I heard of a story about two gamblers that got into a serious fight on the grounds that a bet they merged an amount of money equally to place using the online account of one person among their two. Luckily for them the bet won. But something happened, when it got to the sharing formula of the total amount won the owner of the account insisted on taking a lion's share since it was his account that was used in placing the bet. The latter refusing to accept it that way they got into a serious fight. How pathetic!
What could make you get into a fight with your fellow gambler? And would you agree at anytime to double cash with your fellow gambler to place a bet using his account, on the notion of increasing the potential win.
Well... what is the point here with your idea, there is no difference with a business, etc. If there are disagreements, the discussion will always exist.
Now, if we go to the real problem that is related to gambling, we have the classic of slot "free" that is "occuped", so, someone is playing it for hours and other personas comes and wants to take it, because yes, but the other person went to the bathroom, etc I have seen great discussions.
At the poker tables someone once wasn't on his turn but said all-in and there was big trouble, etc. There are cases directly related to the games that are complicated.
