"Sliding doors manual" joke

At a place where I used to work, there is a huge sliding door
The sliding door is operated by two three-button-panels. One inside
the building and one outside.
One button has a left-arrow on it, the button in the center is a red
one with the word "STOP" on it, and then there's a button with a
right-arrow on it.
1. When your are operating the door from inside the building (The
panel is to the right of the door):
1. If the door is open and you want to close it, then the right button is
the right button, the button in the center is an emergency-stop-button
and the button that is left is the left button.
If, on the other hand, the door is closed and you want to open it,
then things get a little trickier. Because now the left button is the
right button, the button in the center is an emergency stop-button and
the button that is left is... the right button.
2. When your are operating the door from outside the building (The
panel is to the left of the door):
If the door is closed and you want to open it, then the right button
is the right button, the button in the center is an
emergency-stop-button and the button that is left is the left button.
If, on the other hand, the door is open and you want to close it, then
things get a little trickier. Because now the left button is the right
button, the button in the center is an emergency stop-button and the
button that is left is... the right button.
If I have left anything out, please write me.
Right?
Lefty?
