Every time I receive a daily quest I rarely do it immediately. I'll do some other quest, or maybe even play some other games. By the time I completethe the daily quest, I'm handed a new one immediately because a day has passed since I received the last one.
I've just handed in a quest to Numani-Rasi in Ald'ruhn (a quest I probably received over a week ago) and she doesn't have a new one for me
