Don't you think that if you have time to read your book then you don't really need to poop yet? Why not just wait until you're ready to go in?
Who says the readers are waiting while they sit? What's the rush out of there? Maybe this will make the concept easier for you to understand -
Restaurant: sit, eat, drink, chatter, coats, car, home.
Toilet: sit, splash, tinkle, read, wipe, wash, out.
