The tub is full...

You are still sitting in your bath tub, when you recognise that the next appointment is imminent. Therefore you would like to empty your bathtub in as short a time as possible.

You think about: When does the water drain off more quickly? Will it drain off particularly fast, if you sit in the tub? Or will it drain off more quickly, if there is only the water in the tub and not your person? Or will it always take the same period of time?
