Humans suck they’re inconsiderate of things around them. Got this 6’3 person who decided to stand in front of a 5’5 person. Can’t see.
I’m 6’4" and just checked behind me to see if a 5’5" person was behind me. He/she might not be inconsiderate on purpose, they may just be unaware. I’m usually pretty receptive to being asked to move.
