Self awareness

Yesterday I was trying to leave a store and there was an extremely slow person in front of me. They centered themselves in the middle of a large double door, making it impossible to go around them on either side. I found it frustrating,  although I did not press into them or say anything.  Today, I was walking down a back aisle with a cart and a woman started to turn out of an aisle in front of me. She then stopped and backed up and stated she's slow. Such a difference. I find very few are aware of their surroundings. It's okay to be slow, but kind to be aware and not inconvenience this around.
