I hate it when I’m on the elevator going down to the first floor, and upon the doors opening, someone rushes right in without first checking if there’s someone exiting. This annoys me because 1) it usually results in a shocked look on my face right before this person runs into me, and 2) it’s a “duh” kinda moment, because we’re arriving on the first floor, the main floor, and usually a person would be exiting the elevator.
This annoys me more than when someone pulls the cord on the bus to signal for the next stop, and then someone isn’t paying attention and does it again without checking. Yes, I realize this doesn’t affect my life at all, because after the first time it doesn’t ‘ding’ anymore. But I just wish people paid more attention to their surroundings.
