How do you get free tower bucks in tiny tower

I do know this cheat. First, you must have the sushi bar. It will not work with any other store. Then, you have to have a free space to hire someone. Then, you tap the hire button and then quickly touch the bottom of the screen. NOTE: You must have at least 15 bitizens living in your tower for this to work. It will say "give "Null" the job at the sushi bar". NOTE: "null" is no one, so this won't take up any hiring space, but you must keep at least one job opening for this to work. If you select yes, then it should say" CONGRATULATIONS you have given null their dream job and have earned 2 free tower bucks". The best thing about this cheat is that it hasn't been patched yet and you can keep repeating this cheat over and over.
PS. Just as proof, I currently have 25 floors in my tower with 43 bitizens living in it.
