Some context, I requested my Uber driver at 4 in the morning at my university department building. So I was a bit tired and yawning a lot throughout the ride. However when I entered the car I always be respective, nice and say “hi, how’s your (day/night going)?”. We didn’t talk at all throughout the entire trip. Then when we arrived at my place I said “thanks and take care” , then he proceed to give me an one star to my face, without even saying why I was rude at all, ( the only reason I could think of, is I yawned a lot), so out of frustration I in returned gave him an one star.  Another thing I always remember to try to close the car door as soft as possible while still able to the close the door, as I got complain before for shutting the door too hard.
