Someone suggests to Noel Stevenson that the secret life of billionaires usually includes two side by side dishwashers:
“…I had a friend suggest getting two dishwashers, so you never have to empty it.”
While you might need to own double the dishes, it is true that you may never have to empty the dishwasher. Although, if you are a billionaire, you may wish to consider a butler or housekeeper that takes care of those things for you.
