Oh that makes sense, they do have a separate process there to handle all the people that are convinced that there’s an in person process, but it’s still just a mail in ballot and a county drop box, they just don’t have time to try and convince you that you aren’t special.
One of us is an elections official in Washington, it isn’t you. King county is having a special election right now, if you are in a participating district, ask them what the difference is between the “in person” ballot and the mail in when you go in. It’s the same ballot.
