Question:
I put money into a vending machine to purchase a bottle of water and two bottles of water came out. Am I able to keep the extra bottle of water or must I find the owner of the machine and return it to him? The machine was located in the the Supreme Court house in Brooklyn NY.
Answer:
You need not find the owner of the machine to return the extra bottle.
However, if you wish to create a Kiddush Hashem by tracking down the owner, and, explaining that you are Jewish, returning to him the extra bottle, you may certainly do so.
