SUNNY: Another new [maid], Emily?
EMILY: Yes. The last one only made it through one evening. Thoroughly nervous creature.
NATALIE SWOPE: What do you do to them, Em?
EMILY: Oh, the usual. Clean this, cook that, sacrifice a virgin on your way out.
SUNNY: [laughs] The things you say.
Emily’s friends are teasing her about her inability to keep any maid longer than a week (where does this everlasting supply of new staff come from, I wonder?). She is apparently well known in her circle for this, and Liesl seems to have quit after just one night of having to witness Richard and Emily fighting on the stairs … no wonder she was “thoroughly nervous”!
Emily jokes that she makes her maids sacrifice a virgin, a stock trope in films about Satan worship. She’s well aware that she’s considered a bit of a “devil” as an employer. Note that Emily’s friends enjoy her rather wicked sense of humour, a trait which she and Lorelai share.
Emily is careful to hide the fact that her fight with Richard is what caused the maid to quit. She is both too proud and too loyal to let her friends know that she is currently quite unhappy.
(We only find out the name of Emily’s friends from the credits).
