Greedy? That's silly. Imagine, say, that A likes chocolate and B likes fruit. They both have one piece of their respective preference. Then imagine that C likes both, but has one piece of whatever they feel like at the time. Next time, they have a piece of the other thing. All three are eating the same quantity, but C is eating an equal amount of both foods, rather than exclusively consuming one type. Does that make C greedy? No. If C scoffed as much of both as they could get, then yes, they'd be greedy. The same could be said of A if they ate a whole box of chocolate. As it is, C just has a wider preference for food, but still eats in moderation. If C stopped eating fruit and adpoted A's eating habits, no change in the level of consumption would've taken place, so accusing C of greed is unfounded, and rather odd.
