Wow, what a remarkably bad analogy. Shall I expand on it for you? I hope you don't polish your own shoes because despite the fact that the hotel puts a polishing tool in your room, if you were to actually use it, you'd be cheating a shoe shiner out of a couple of bucks. I hope you don't shave yourself in the morning 'cause you're denying a barber money to put food on his family's table. Do you dress yourself? Think of all the valets out of work due to your selfishness!

Now, if you want a reasonable analogy, try this on for size. You make your own bed in the morning and hang your towel to dry. You put the "No service" sign on the door because, well, you don't want anyone servicing your room. The cleaning staff comes in anyway because it's their job. Annoyed?
