The people giving away the food were not charging for it: therefore they were not 'serving' the food; they were simply sharing it.
This incident is symptomatic of the moves being made: in America and across Europe, toward totalitarian statehood. This might sound a bit extreme but it is, nonetheless, still true.
A little while back American police were physically attacking, and arresting people for doing no more than dancing at a monument in Washington (was it the Jefferson Memorial?). Dancing is not now allowed. But the wholesale trampling into the dirt of the American Constitution: America's finest monument, by the government, banks and authorities continues unabated.
What the authorities have realized is that there is a growing awareness: amongst ordinary people - all around the world - that they do not live in democracies. People are beginning to see through the shallow charade that masquerades as democracy.
There is a great reckoning coming. And the authorities are chipping away at your civil liberties in preparation for when it arrives.
