Private Sergeant

 

It must be the way to the opposite of an officer's lounge. We were at a garden when we saw this, but you never know?

Whoops, I accidentally scheduled this for last Thursday, but here it is again when it was supposed to post. Oh well.

Explanation: "Private" can mean "not for public" but also it is a military rank.
