I work at a fairly busy hospital and do a fair share of walking around the facility with many many twists and turns down hallways. Some on these corners have the semi-sphere mirrors that allow you to see around the corner, but most do not. Around 50% of the time when coming to a corner you aren't able to see around, I will nearly level a person taking an inside turn, and then they will look at me like I'm in the wrong. I know not everyone drives, but why do so many people just ignore the general rules of travel (I'm in the U.S. so walking on the right side of the hallway, etc)?
