This picture always makes me chuckle. In Britain it used to be a daily ritual to put the empty milk bottles on the doorstep for the milkman to exchange for new full ones. Clearly, here in the Mosel, this is what some folk do with the empties although I somehow doubt anyone replaces them daily with full ones!
Now that has just given me an idea for a great business – get one of the old redundant electric powered (yes, electric powered vehicles are not something which appeared in the 21st Century) milk floats from Britain and use it for daily doorstep booze deliveries. It has to be a winner!
