There is Derek's safe at the end of America, and there is only one?

A scene after the demo, an underground place, where there are three runners and many listeners, needs to hide safety documents in a counter drawer similar to a small shop on the left hand side. The content is that Derek, the bookstore owner, asked him to put things in the safe with the password attached. The safe is on the right, almost opposite the place where the paper is taken, and he can get 50 copies.
