<human>: Can you give me the gist of the text in a nutshell?

[So, I know that this is Reddit's stance on faith in humanity] but there are moments which prove that people don't **always** suck. 

Case in point:

I was travelling with my grandmother in 2010. We were in Stuttgart for a week, and afterwards we went to London as part of the larger trip. We didn't think we would exchange any of the Euros we had left over, and since I would be moving to Germany several months later, my grandmother decided to entrust me with the remaining cash as a late birthday present. Since I had nowhere else safe to put the cash, I put it in my wallet for the time being (I would have put it in my checked luggage, but I've had issues with that before).

We arrived in London, and got a cab from the airport to where we were staying. I didn't notice anything was amiss until about an hour after we had settled in, when the doorbell rang. I opened the door. Lo and behold, there stood the cab driver who had brought us from the airport. I ask him what the matter is, and he tells me that he had found my wallet in his cab. I have no idea how it fell out of my pocket, or if I had taken it out and left it there, but it had been left in the car. The cab driver had gone out of his way, possibly missing out on the chance to get another fare, hours after dropping us off, to return my wallet, which had a few hundred Euros in it (the Euro is weaker than the Pound, but still, it's not a small amount of money).
<bot>: a cab driver in London went out of his way to return my wallet, which contained a few hundred Euros hours after having taken us to our destination, effectively restoring my faith that humanity isn't entirely jerks.
