The Useful 'useless clock'

Got a clock with some fancy labels/ advertisements. Where should I place it? Surely, not in the formal room or in any rooms where your guests would easily notice and judge you mean/ stingy.

For those who have the habit of getting lost into thoughts while the showers chills you. You might find this one helpful. Keep one of the unpopular, low-price clock in some dry area in the bathroom.
