I work in hospitals a lot, and most hospital workers follow traffic patterns in the corridors just like in automotive traffic i.e: keep to the right side, get flat to the wall when you see a doctor or nurse running or a patient bed coming at you, and when turning left at an intersection stay wide. We also have a tendency to walk at a brisk pace because we have places to be. But I hate it when slack jawed locals mindlessly plod down the middle of a corridor, or even worse cut off the corner in a turn and plow right in to me when I am turning right in an intersection. Seriously people, I know you or someone you know is sick, but that's no reason to impede the flow of traffic. And there are zero sightlines around corridor intersections so keep it in mind before you slog around a blind corner and end up eating someone's collarbone in a collision.
