This Bathroom Law Confusion

One of the buildings I work in has three employee washrooms: one male, one female and one with both symbols on the door. I call it "Undecided".

Separate but equal, eh? In fact, the Undecided washroom is anything but equal since it's not wheelchair accessible and it's also used for storage so it's barely accessible at all. However, it does discriminate against all wheelchairs regardless of gender.

It would be pretty stupid to pass a law regulating single-occupancy bathrooms by one gender or another.
