One thing to ponder: when the week's godlike alien kicks the Enterprise
in the groin, and the bridge shakes enough to throw Lt. Leslie across the room and back twice, does the rest of the ship necessarily shake, too?
I mean, yeah, McCoy has his desks full of unsecured, fragile bottles and delicate instruments. But the ship also supposedly has an inertia-damping system. Just because we see the system fail to cope with shaking inside one room doesn't necessarily mean that every location shakes badly enough to create a mess. Perhaps the yeomen only have to clean up every third cabin or so?
