Quote from George in The Postponement
George: I will never understand the bathrooms in this country. Why is it that the doors on the stalls do not come all the way down to the floor? Susan Ross: Well, maybe it's so you can see if there's someone in there. George: Isn't that why we have locks on the doors? Susan Ross: Well, as a backup system, in case the lock is broken, you can see if it's taken. George: A backup system? We're designing bathroom doors with our legs exposed in anticipation of the locks not working? [snorts] That's not a system. That's a complete breakdown of the system.
