I've got a butler in my Bridgeport game with the ghost/vampire triplets. One thing that I found odd is that he would repair things only a little at a time. He would work on the television, then go mop the bathroom (broken shower), then to back and work on the television, then go mop again, etc. He didn't stay with the television until it was fixed. He also does only the bare minimum with the toddlers. He'll feed them when they are in the yellow on hunger, put them in the crib when energy is in the yellow, etc. He also cooked my Sim a bowl of mac and cheese without being asked.
