What would you do if you found a wallet full of cash on a public bench?
If I found a wallet on a public bench, the first thing I would do is to check the wallet for any sort of ID or drivers license, in case I recognize the person. If the wallet had an ID but I didn’t recognize the person, I’d be sure to drop it off at the sheriff’s departnent so the police can get it back to the owner. If the wallet didn’t have any sort of ID, I’d try to ask around to see whose wallet it is. If no one claims it, I’d pick it up and send it to the police department for them to dust it for fingerprints.
But no, I if saw a wallet full of cash anywhere, I wouldn’t take any money out of it. Even if I spotaneously become homeless, I would try my best to return the wallet to its owner.
