Picture this. You are at a nice party/reception, and there is a buffet. You're hungry, but etiquette dictates a proper way to serve yourself. You don't just pile your plate with the food you like. Maybe you take a little bit of this, take a little bit of that. Or, as this guy did, try another tactic.

 

Now that's the way to do it. People won't think you're a hog. They'll think you're passing food. Good move.
