A big, muscular man was using the stairs to get to the top floor of the casino, his hand constantly gripping the railing. Every time his 150-pound body stepped on the wooden stairs, the sound of creaking wood made the man more careful.
In fact, even if the stairs collapsed and the big man fell down one floor, nothing would happen, but he was a human being. If we consider that the greatest fear among human beings is directed against the darkness, which has no physical body and cannot harm people, it would make much more sense for this big man to be afraid of falling down the stairs of a two-story building.
As the big man climbed the stairs he silently cursed his boss who didn't want to spend money to fix the stairs and finally successfully made it to the second floor.
