My butler's just fantastic, except for cooking too much. I've had him a long time and began to worry that he'd age up and retire, so I added him to the household. It turns out he was 1 day from elder, so I showed him the replicator and the ambrosia inside and voila, an unpaid butler who loves the family. The best part: he no longer cooks until I tell him to. He has level 10 repair skills, level 10 cooking, Natural Cook, Neat, Family-Oriented, Brave, and Frugal traits. I almost squirted nectar out my nose when I saw Frugal, given his frequent lobster thermidor meals.
