I hate that moment when you enter a building and look back to see if the person following you is close enough to hold the door. If you hold it too soon you run the risk of making the person feel rushed, let it shut and that person will be talking about you around the water cooler. Case in point, I held a door for someone who was too far away, they hustled up as to not make me wait, but that caused them to drop some papers and binder and ultimately caused the person and myself no benefit. Doors should have a line, like a free-throw line, marking when it is appropriate to hold the door … maybe not.
