> It is easier to build two chimneys, than to keep one in fuel
Poor Richard meant spending. Read it as a propane man: it is easier to sign two new customers than to keep one in fuel all winter. Signing takes an afternoon. Keeping takes seven months of deliveries that show up before the gauge says they must. Before you spend on the new-customer push, count what it costs to lose one you already have.
