Those things are damn difficult and expensive to maintain. They demand you to move the furniture every week (even if you calculated the optimal position of them), buy new clothes every second week (although you bought clothes which were designed to last at least 2 world wars), and make you do all kinds of stuff which are highly uneconomical, just because they don't find it interesting to sit in front of a computer screen 8 hours a day with a beer bottle in their hand, and enjoy life!
