This is a door on the brand new public restrooms at a Santa Monica, California beach near Montana avenue.

These are individual stalls. One per person, each with its own door. Does anything seem missing?

How about one of those signs that show whether the stall is occupied or vacant? The temporary portable restrooms that were there during construction of this building had occupied/vacant signs. Isn’t it bizarre that the new building lacks them? Hundreds of people a day use these restrooms.

I know they make occupied/vacant signs for this type of door. I’ve seen them.

In ProxThink terms, an occupied/vacant sign uses Connected Independence to increase ProxAwareness. You know whether someone is in there independent of having to knock or try the handle.
