We are up on the top floor. Heading down, I learn that some elevators have secret codes which have been implemented for folks like the fire brigade.
If for example the button for floor 5 has been pressed but you want to skip it - press it 3 times to void it -the elevator will then skip that floor.
This code is also useful for when annoying kids press a load of floor buttons just before they get off the elevator giggling leaving you to stop at each floor.
I just noticed that this elevator has floor "4" - in Japan (and in some Chinese speaking countries (and Korea too for that matter)), the "On" reading of "4" is "Shi" which is also the pronunciation of the word "Death" which is why many buildings dont have a 4th floor.
