Never take more than your share - whether of the road in driving your car, of chairs on a boat or seats on a train, or food at the table.
Emily PostPeople who picnic along the public highway leaving a clutter of greasy paper and swill (not a pretty name, but neither is it a pretty object!) for other people to walk or drive past, and to make a breeding place for flies, and furnish nourishment for rats, choose a disgusting way to repay the land-owner for the liberty they took in temporarily occupying his property.
