Are Butlers ok to play with and where to eat?

I haven't had any problems with butlers after I've figured out, that they need a double door to the room, where their beds stand, to function right.. Together with a nanny, my big sims family never run out of any food. The only minor issue was that he loved to stay in front of the television and check for dust where my sim wanted to watch the TV show, it didn't interfere the fun creating.
