OK, these are very practical solutions, and everybody does them at some point in time. But the problem with all these solutions is that either my friend or I have to wake up at a torturous 9am. And yes, I know you in Singapore who have school at 6 or 7, are going !!! but remember other factors such as the Melbourne winter...and the Melbourne winter. I could write a regression equation for you, and test the sensitivity of the model, but I'm too lazy. So I was wrecking my brain and thinking, how can I guarantee a table, without having to wake up at 9? And then like an apple falling on Thomas Edison's head, I got my answer.
Place "OUT OF ORDER" on the table. Of course coupled with the infamous "SORRY FOR THE INCONVENIENCE CAUSED."
I'm a genius.
