As you make your way towards the exit of Vaas' camp, you will come upon a table surrounded by luggage, purses and cocaine bricks.
On the table will be a camera, a lighter, a map, and phone.
Your objective will instruct you to grab them all, so hit the action button to pick them all up.
Uses[edit]
The lighter is used to light up molotovs.
This ends up being a pretty key piece of functionality, since fire plays such a large role in the game.
The lighter can also light up dark enclosed areas, although you have a flashlight for that in most situations, excepting a late-game cutscene.
