You cast your eye over the potential weapons. These include: an empty beer bottle; a half-full glass; seventeen different boxes of snuff; a potted plant; a walking stick; beer mats; a pipe; and two old men. Using the weapons to hand, how do you exact vengeance on the idiot on the bar stool?
EDIT for room plan: you're not sitting on a bar stool yourself. You're at a table on the other side of the admittedly rather thin room.
