I think you do, you just don't need to notice it. If you spilled it in the International Space Station, you'd probably respond differently even if you didn't have to stop and contemplate the physics of the situation.

I think they may have been referring to the fact that in the case of a spilled drink there's a shortcut from the sensory input to a motor output. Maybe you reach for the falling cup, maybe you back away to not get spilled on. These don't really require the conscious mind at all.

I don't think that we need to be aware of the reasoning our minds are doing for it to constitute reasoning.
