It's better to stay away from machines that have Credits left over from other people rather than having problems and causing big problems. It's best to avoid and stay away from them even though I've never played games on offline casino machines but that method doesn't sound good if we play on machines that still have other people's belongings in them. because gambling with our own money really makes us really comfortable playing.
I would also probably never try to take someone else's rights because it would make me feel guilty if someone else left the money and then came back with new money for that machine, the right thing to do would be to look for another machine that doesn't have other people's remaining Credits, because it will be safer for us to play.
Yes, it is a safe way to avoid problems arising because we could be accused of taking someone else's property in the casino. We don't want to be accused of anything by other people or casino security, so it's better if we move to another casino machine. I have never encountered this but at least that is what I will do so I don't experience any gambling problems.
Taking someone else's rights is a mistake, especially since it doesn't belong to us and we don't know the real owner. Therefore, we should look for the owner and if we really don't know, we hand it over to security and let them look for the person so that we can gamble comfortably.
The person who left such balance might comeback on where he gamble and claim something he left so for not telling the truth we might get a huge shame especially if the person is so sure that this is the machine they used. So its better to be more honest so that not problem will arise and let the casino worker handle that situation so if the costumer comeback and ask for the balance he left then he can give the money left in any form the casino workers want.
Although its really tempting to stay silent especially if the funds left by previous player is so huge but we need to declare it so that we can get peace of mind while playing and we will not get accused that we are stealing their balances left on the machine.
