As requested by stargazer, I shall continue sharing this real-life story that happened to me.
I once left my phone in a taxi cab after a long day of work. Only realized it as I was prepping for bed - not a great feeling, knowing it's gone and most likely never to be seen again. But then, at that moment, the taxi driver actually contacted my husband through the taxi booking app! My husband promptly arranged to meet him at his current location, which was quite some distance away in the opposite part of town.
When the cabbie arrived, he explained that he found my phone while cleaning his cab - it was hidden somewhere in the backseat, and I didn't even realize I lost it! What were the odds of that?! He then proceeded to return my phone, refusing any attempts at rewarding him for his honesty. It really made my day, knowing there are trustworthy people like him out there.
So yep, lots of good samaritans in this world!
