You drink the Green potion. At first, nothing happens. Then you hear a noise; something fell from one of the shelves in the store.
You move to investigate and realize that it was a box stuffed full of money. As you kneel to pick it up, you hear a metallic clank from where you were just standing. Something fell from the ceiling, and would have hit you had you not moved.
Then your phone buzzes, informing you that you were chosen as the winner for a raffle you entered a week ago.
It's pretty clear you have consumed a luck potion.
