When the Lady Morelin (Elayne) and her maid Nana (Nynaeve) stay at her inn, she offers them a private dining room and lets Nana do everything for her lady instead of having her girls help out. Elayne is not sure whether the innkeeper wanted to get work out of her way or if Amadician nobles demand this.

"Mistress Alfara had been sure that only the Lady Morelin's maid, Nana, would know how to serve her properly; ladies did require everything just so, the woman said, as well they should, and her girls were simply not used to ladies." (Elayne; The Fires of Heaven, Chapter 13)
