Stair in the kitchen

You believe that the elevator would cause to much attention by whoever is in the building. And it would be possible that there are more than one players around. In this case it would be likely that at least one other player guards the stairs in the center. So you decide to go through the separate stair in the kitchen.

Slowly and always ready to react to surprise attacks you sneak up and take a look around there is nothing unusual in this floor. There are only afew desks and offices and an empty janitors room is at the side. Nothing seems like a good place to hide a package with food or items. And it also seems that nobody is in this floor. But you also can't see another stair to enter the second floor.
