Which Door Should I Choose?

ANNOUNCEMENT... There are 2 doors to use whenever going through a doorway. One door is used for one way and the other door is used to go the other way. It's a very simple concept really. I don't know why people feel the need to wait until a group goes through one door before they go the opposite direction through the same door. I guess they don't know how the whole 2 door thing works. Hopefully everyone now knows the concept, or at least i hope so. :)
