“People have been counterfeiting bottle caps forever, but it's always been small scale. A bottle cap press is a whole other threat. We can't have anyone devaluing our currency by mass producing new bottle caps.”— Alice McLafferty
Go to the headquarters and locate the bottle cap press, which is found in the shipping area. Once in the shipping area, there are four or five Sunset Sarsaparilla robot employees that are hostile. The press is between the two stacks of crates in the middle of the shipping area behind a dead worker and near a box with six bottles of Sunset Sarsaparilla (the only ones found in this room).
If one hasn't already, a Mr. Janitor can be manually activated with a Science of 50. Use the terminal next to the robot to activate him. After Mr. Janitor cleans a few rooms, it will dispose of 500+ caps in the garbage can closest to the room one found it in. Do not talk to other robots while it is cleaning. This may cause it to stop cleaning and attack. Mr. Janitor will not activate a second time. After activating Mr. Janitor, wait outside the room for a few minutes, then he will come back and put the caps in the garbage can outside the door with the 250 to 600 caps.
The cap press cannot be used to produce bottle caps.
