Not anywhere I've ever been. They're all multiple stalls, often without a locking outer door. I live in the west, they may be different in the east.
The inevitable response is to eliminate public restroom
facilities altogether; this is in fact the case in some
NYC chains and public library branches. In some cases
the elimination is by posting an “out of order” sign when
the facility is operable. This entails a loss of business
since many patronize the cafe/store bc of the restroom.
