Maybe They Were Getting Paid By the Letter

I was pulling out of a driveway and a street ahead of us had a sign that said, "NOT A THROUGH STREET."

Claire asked me what that meant.  I explained that if you turned onto that street, you couldn't use it get to any other streets.  It didn't go "through."

Then Claire asked me, "Why didn't they just say 'NO OUTLET'?"

I don't know Claire.  I don't know.
