A system for selectively providing access to a consumable. The system includes an enclosure having a hollow interior for holding the consumable. A door mounted in an opening in the enclosure provides access to the interior of the enclosure at a time when the door is in a substantially open position and prevents access to the interior of the enclosure at a time when the door is in a substantially closed position. The system includes a locking mechanism for releasably locking the door in the substantially closed position and a complimentary relieving key for selectively releasing the locking mechanism.
