Finding Lost Cell Phone
While travelling last week I had my cell phone out, and I set it down and couldn't find it when it came time to board. I looked all over and thought it was just lost. I couldn't pull all my bags apart, as I didn't have time while boarding, so it was still possible I had it. I figured, however, I would not give it up entirely until I tried one more thing to find it.
I had been using my Bluetooth headset thingy, and I knew it had plenty of battery, so chances are if it was in the bag, the Bluetooth was still on. So when I got into my next destination, I pulled out my laptop and did a Bluetooth device scan. Sure enough, there it was. Either it was in my bag, or the person who stole it was still nearby.
