It is unimpressive to not hold a door open for the next person coming through. After a satisfying workout at my gym, I was walking behind a man who was exiting at the same time. He was only about two feet in front of me. As he walked through the door, he let it close behind him, almost hitting me in the face. Was he being intentionally rude? Was he preoccupied and focused on other things? No matter whether an offender is being a jerk intentionally, or is simply oblivious to how his behavior is affecting others, rude behavior instantly makes a negative impression. Be aware!
