I don't approve of a WASD movement scheme.
Mouse-clicking will be far more "fluid" and realistic I think. WASD will have you running up to the stool, continuing to jog into it, pausing for several seconds as you open up the mouse menu, and sit.
Mouse-click will have you enter the bar, click on the stool from the other end of the room, and go to sit on it. Your character will walk from one end, and immediately go to sit in one motion.
WASD...people running around in bars and clipping off pillars, bleh.
