Yesterday, but...
Parked in bit of a tight spot in the busy grocery store parking lot, and decided to fold-in my mirrors so the adjacent cars would have an easier time leaving. But with that distraction, I left my phone in the dash phone holder AND (probably*) forgot to lock the car.
Realized I my phone wasn't in my pocket after entering the store, but decided not to worry about it, as it as in the 'locked' car. Walking up to the car I hit the unlock button (not sure if the car was locked or unlocked, but now it was unlocked), popped the trunk and put the groceries in, then noticed through the rear window the phone was not in the dash phone holder. I figured, oops, I didn't lock the doors and it was too tempting for a passerby (the screen would have been "on", calling attention to the phone). Before I got in the car, I'd resigned myself to having to get another phone, but when I got in the car, the phone was on the driver's side floor.
My theory is that someone noticed the phone, noticed the unlocked doors, and did me a service of 'hiding' the phone on the floor rather than leave it so obviously steal-able. It made me pretty happy that I avoided the expense and hassle of getting a new phone, and it also gave me a bit more confidence in humanity.
* The 'probably' is because that phone holder has been known to spontaneously eject the phone onto the floor. So the car could have been locked and the phone popped off the holder by itself. But I'm thinking more likely is that some good person helped me. That's a better story to believe.
