Human: Produce a detailed written description of a eerie scene inside a tavern with a bar, sawdust, and sconces. Assistant: 
A blackened, smoke-tinged window occupies the upper reaches of the southern wall of this dive bar. Sawdust covers most of the oaken floor, and bronze sconces adorn the paneled walls. A horseshoe-shaped bar is positioned prominently in the center of the taproom. A lone worker sweeps up some broken glass and mugs strewn across the floorboards, while a strange, still silence fills the air.
