Architecture - Stairs - Let's take a peek upstairs Poster

So, your invited to stay in a lovely mansion. The butler, asks if you want more sugar in your tea, but your distracted by that lovely staircase. He repeats the question and distracted you say, I like the sugar, not tea so much. So then he asks, would you like more tea for your sugar then? You say, yeah sure, that sounds good, and the butler goes back to the kitchen. You on the other hand want to see what's upstairs. So you drag over a lamp to where you were sitting, and place your jacket and hat on it. And start sneaking upstairs. Then the butler spots you, even though you thought your lamp fill in would certainly fool him. He asks, can I help you sir, and your like, um, no, I just need to do something. He asks, what? You say, I, uh, dropped something up there, yeah, that's it. So you dash up the stairs before the butler can react. As you look back to see how confused the butler looks, you run right into a wall and fall back down the stairs. The stairs are just for show sir, there is no second floor. Here is your sugar with a bit of tea mixed in.
