“When I walked out the driver was there waiting at the hospital. he got out of the taxi and opened the door for me and helped me in the cab even though I was okay! 
He offered to carry my bags up, because he remembered last time that I needed help. Both times he’s told me he will wait outside with his lights on to ensure I get inside safely. It’s something that doesn’t have to be done the fact that he does shows that he goes above and beyond for not only me, but I would assume all customers. 
I felt like I needed to pass along my additional thanks, and compliments to the driver and 13cabs!”
