Last week, I was running a little late on my way to my first day at a new job in East London. I had injured my achilles heal a couple of days before and didn't want to put too much pressure on it by running to the tube station so I decided to jump in a cab just to get to the station.
The cab driver was really warm and friendly and happened to ask me where I was off to. So, I told him how I was on my way to start a new job and was running a little late to get to the tube station. En route, about half way there, he realized that the road was closed ahead and told me that as a result this is as far as he'll be able to take me. Of course I said no worries and pulled out my wallet to pay him for his services.
At this point, he turned around and said to me with a huge smile, "Don't worry about it. I feel bad that I couldn't get you all the way to the station when you are running late for your first day of work. This one's on me! Good luck with your new job."
I was floored -- London cabs are generally really expensive, and he really didn't have to do this for some random stranger off the street. But he just felt like being nice and bringing a smile to someone else's day and so he did it anyway. Thank you, to this anonymous cab driver, for bringing a smile to my face every time I think of this experience.
