Well, when something like this happens, it's very unpleasant & can ruin a good mood. After an experience like this, the player will never want to return to that casino...
That will surely make me get out of that casino and will never get back to them after getting my money. It's a very unpleasant experience if you're there to have fun and out of luck you've won. And them, they'll just talk about how to delay your cash out and then refuses to give the money.
If this happens to all players who can't cash out their winnings, it's likely the casino's fault. However, if this problem occurs with just one player who wins but can't cash out, it's likely the player's fault. However, there's no guarantee that the player is at fault or cheating. However, the casino will certainly do its best for the customer's safety.
There is a possibility of tripping from the casinos end if they do this to one person. We can't conclude that it's because of the player's fault. Because if proven that the user is not guilty, the negligence is on the casino.
