Knowing when to leave a tip

Recent I found myself running late and so instead of getting the bus I had to get an uber to make my train on time.

And so there I sat in the back seat feeling slightly anxious and playing the soothing sounds of canon in d major over in my mind in the hopes that it would keep my heart palpitations at bay.

It was my fault that I was running late so I resisted the urge to ask my driver to step on the gas. Instead we made small talk and he commented on what a lovely name I had and asked me where I was headed for the day.

In the end I was earlier than I expected and my driver left me with some much appreciated words of positivity. And so as I headed into the station to platform 4 I decided to tip my driver.
