i had a meeting with a multi-billionaire a while back (taxi drove around the block in central london for a while as we searched for the house until i realised.. the whole block was the house). he ended up complaining how difficult it was managing employees and in particular dealing with all the household staff. i asked if it wasn't possible to do without them for a few days. he seemed to consider it for a moment before sadly replying: "Do you know.. I don't think it is.".
