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?
Legally? or conscience asking mate? because what matter or whatever connect to that amount still that is not yours.
the way you posts this here is looking for justification about that act even though we knew that it is not our money and need to be reported to the casino staff for proper action.
and besides we don't know what will happen even if you tries using that amount if will be allowed to withdraw ot cash out?
just play with your own money and care nothing about those forgotten money from other players .
It may be possible if no information or anything shows that someone is the owner. But we should not do it because the credit is not ours. We also don't know if anyone knows about it but they keep quiet because it doesn't belong to them. You can try asking the casino staff if you find it so that you won't experience problems gambling. If you use the credit, you may be accused of being a thief, especially if the credit owner returns to the slot machine and wants to take the credit back. That will be a problem for you. And the casino will know if you have used those credits.
and that means being stolen mate., the house has a rules that everything must be surrender so doing such will turn not to be a best interest for all of us
