Victor Hugo,
Les Misérables — Volume 4, Book Tenth…
“ At the time of the insurrection of 1839, in the Rue Saint-Martin a little, infirm old man, pushing a hand-cart surmounted by a tricolored rag, in which he had carafes filled with some sort of liquid, went and came from barricade to troops and from troops to the barricade, offering his glasses of cocoa impartially,--now to the Government, now to anarchy.Nothing can be stranger; and this is the peculiar character of uprisings in Paris, which cannot be found in any other capital. To this end, two things are requisite, the size of Paris and its gayety. ”
