## Hubble
In Hubble there are several storage places where things can be found when they run out in the café:
- The back storage
- The storage space behind the kitchen. This is where the bartenders can leave their personal belongings when bartending. Among others, all food reserves, coffee items and almost all drinks have a reserve here.
- Downstairs drinks storage
- This storage is found downstairs going straight left from the elevator. Card access is needed for this storage. This storage is where all of our booze is stored, as well as the big soda and beer keg reserves. The two 1000-Liter beer tanks are also found here.
- Internal Solow
- This storage is found downstairs as well, going right from the elevator. In this storage almost all non-consumable items of Hubble are stored.

- Containers “bakjes” (sauce/fries) – Storage

2. Put it in the storage (in the back for Hubble, on the container with empty kegs for Meteor)
4. Bring in a full keg

2. Connect the coupler to the new keg.
3. Lower the coupler straight onto the valve.
4. Slide the handle back into lock position.
