There is a general rule in land based casinos that a gambler shouldn't take credits left on a slot machine by someone else. Basically, from what I understand, if there is still credit showing on a slot machine. Don't cash out or add to your money you put into the machine. Right? The question is if you find a cash out voucher resting on the machine itself or on the seat, can you legally use it?
Very good question.
I will give you one example, this is my personal experienced wit this kind of scenario. I honestly didn't know that there was money on that particular slot machine an so I put some money on it because I wanted to play that game. However, I realized that there are still little money left on it, so I was taken aback because as a general rule, you shouldn't do that.
And then so the owner comes back, the lady said that she still has some money on it and I acknowledged that yeah it was my mistake and I didn't know that. And so I said that I will withdraw it and give it back to her. But for some strange reasons, she didn't want to and she argue with me.
So I said, WTF, here just it it all, you piece of s**t, it's just a small amount for you. Clearly, I was pissed off and leave that area.
As a general rule, yes, you can't take that credit. You may call the assistance of casino employee and they are the one who's going to withdraw it, just to be safe.
For my case, not sure if the lady is willing to leave the money or just put it a trap to someone like me.
