Do you hold the door open if there is someone coming a few steps behind you?
I always figured that it depended on the direction the door opened, like if I reached a door first and it opened towards me, I would let the person come through first and then go. If they're not there yet, I go through and then hold the door for them. Google says the person who gets there first should always hold the door for the other person, even if you have to wait for them to come.
