Hello and thank you for your question.
My name is ***** ***** I will be happy to assist you today!
As you can see the previous expert never stated that you would be able to be seen at the office as a walk in.
So to answer your question.
Yes MOST TSA offices if you walk in as a couple they will see you back to back. Because you are husband and wife you will be able to be seated together and seen at the same time.
Just let them know when you arrive that you are together so they can put you on priority together.
Please let me know if you have further questions.
