> Since when do you leave a bar with something that doesn't belong to you unless it's somebody else's spouse?
Since you're a good person who wants to call the owner and give it back the next morning before someone less scrupulous steals it? What do you want them to do, leave it there? Give it to the bar staff who you don't know? Give it to the cops who'll simply tell you to contact the owner yourself?
Pick up phone. Wave to bartender. Done. Or pick up phone, drop at police station, done. Or pick up phone, use Safari to place notice on craigslist, done.
Once I exit the property with the phone, I've done wrong. The onus is now on me to follow through and get it back to the owner, not take a half-hearted effort to get through to Apple on the phone before selling it to someone else who is also not the owner.
p.s. I see you've replied to my points in your message. This makes the thread of conversation hard to follow. Yes, give it to bar staff you don't know. It's not your phone, it's not your bar. It's not up to you to sit in judgment over them and find them wanting, especially when you end up selling the phone for your own gain. Likewise, try giving it to the police and see what they say. That would be a lot more convincing than not doing so and selling the phone later.
