So in video games, it's rather common for the hero or protagonist to walk up to people and engage them in a conversation, during which the NPC could offer a quest or mission to the hero. Sometimes these are brought up with the hero having no opportunity to decline, such as Link having to return all of the chickens in the village, and regardless of what the actual quest is, the hero usually talks to the quest giver. Things get a little different in Mass Effect 3. Here Shepard picks up quests by overhearing people talking in public. There is no option to talk with the people and discuss how he, the mighty Shepard hero of the Citadel and champion over the Collectors, could help. Nope. He just hears someone talking on the phone about their need for stabilizers or overhears someone's need for an artifact and there's a new quest added into the journal. Has anyone ever thought about how impolite and awkward that would be for the person, or unfortunate quest giver in this case, when Shepard returns with the item and doesn't explain how he knew said person needed it?

It's even weirder that in the game the people just accept it as is and don't question Shepard for getting into their private lives. Either way, here's a great comic from Vg Cats that does a fantastic job illustrating the situation.
