I completely agree. It seems more reasonable to try and return the property to the company you know it belongs to and not leave something that valuable at a bar. And since Apple didn't want it, well, that's their fault.
And who knows, maybe the guy originally took it to call Gray Powell up the next morning when neither of them were drunk which is the best course of action, but couldn't because Apple nuked the phone. And because he couldn't contact Gray, he did the next best thing and called the company.
