The line comes from Gothic 3, the 2006 open-world role-playing game developed by Piranha Bytes and the third entry in the Gothic series. In the game, gold is the main currency for weapons, armour and training, so NPC dialogue about payment and reward is constant during quests. Short German voice clips from the series are shared widely among its Central European fanbase, and this one survived as a standalone reaction because the question needs no context. It remains popular in gaming edits where a sudden interest in loot is the whole joke.
