Not for all classes mind you! I some cases it's the receptionist instead. (MNK and Scholar off the top of my head)

That's why I say: Put them "all" on the class trainer. And get rid of the sub-class requirement, because that way, it's available right when you hit 30, so it gets rid of the "Red quest" issue as well. Only way to "miss" them then is to not do the class quests at all.
