You can't resist the urge to take the key. It's SO shiny!
Ray returns, and asks you if you can help him, since the shop is so busy today and the Regional Manager Graham is coming to inspect the shop today. Carrying some boxes into the store-room for him, you happen to notice a secret trapdoor behind one of the boxes. The door is locked.
You are carrying: A key.
Do you?
Hit the door repeatedly with a box.
Pummel the door with your hands, shouting 'Why me? Why, God, WHY!'
Use the key in the door.
