Dunno... many years ago I was at a party in a very posh penthouse condo... not so much BMWs and Mercedes in the lot, but Maseratis, Ferraris and limos. It was on the water, and every condo had it's own slip on the dock out back for the owner's boat...

On the ground floor, there were men's and women's dressing rooms, showers, jacuzziis, steam rooms... so, presumably, you could clean up between the boat and your condo...

Anyway, the "super" there told me that he couldn't keep the toilet paper supplied in this area; all the multi-millionaires stole the toilet paper rolls to use on their yachts.
