Some of the adults that have lived in my tower for many years also don't seem to know, or learn, how the elevators work.

They're going down but push both buttons, making people going up stop at their floor for no reason.

They're going up but the elevator is going down, they get in anyway and can't select higher floors until it goes to the basement.

Although some old elevators can be confusing. An old building where I lived had an elevator with hinged doors that you had to pull, then a metal accordion gate that you had to slide. Once the floor was selected an arm would push the gate shut and hold it until destination was reached, then release it. You still had to pull the gate manually then push the door to exit. Friends made jokes about the Titanic era elevator when they visited that place.

Anyway as a city dweller I find them ordinary but I have to remind myself that some people don't encounter them very often.

The one from the picture seems simple enough but if there's a sign, someone got tired of explaining it.

You just know someone complained that they needed instructions.

I'm confused. Why did you take a picture of the elevator?
