The rules certainly drive me up the wall. An event I attend annually in a conference hall has an ongoing joke about being sure you know which chairs in the venue are union chairs, and which aren't. As an attendee, nobody minds if you move the non-union chair, but if you so much as move a union chair a few feet to join an adjacent table, expect to be reprimanded.
