A Good Sign: Liquor & Wine

I passed this half-lit neon sign on E. 14th Street the other night. The narrow liquor store it advertises is out of business; just empty boxes inside. The sign's not much to speak of—just a classic example of its day, and poignantly on its last legs. One thing I wonder: if the shop's dead and there's nothing inside, why is even half the sign still lit at night? Did someone just forget to turn it off when they closed up for the last time?
