last ride of the night, pick a guy up at a local millennial club at 3am. I figured he must have been working because they would have closed an hour ago, and yes. When I got home I looked and found his phone and two empty envelopes that seemingly had once contained his share of the credit card tips for the night. The envelopes were indeed empty and have no value. But the phone. What to do?? The lock screen had his home number on it, so i tried it at 4am, to no avail. I will try it again during the day, but what is the protocol here? I know i have seen it here and can look it up, but it has been a long day of driving, so im just asking. Thanks.
