I'm torn on this one. One the one hand I would love that extra privacy.
On the other, I really value knowing if someone is in the stall next to me and how many people are in the bathroom. If the stalls extend to the ground how am I supposed to scan for legs? Someone could be hiding in there waiting to frighten me! I cannot use the bathroom until everyone has left it. Just how am I supposed to verify that some quick-footed coworker hasn't made their way in during someone's loud flush?
I cannot stomach this game of chance.
