So apparently this Walmart location has become a new "Low Light" store for those who are light sensitive. Not only did it take a while for my eyes to adjust from the bright sun outside but the store looked dingy and dull. The low light also made it difficult to read labels and things for the rest of us. So I just decided they can have that store, I'll go to the other bright, colorful Walmart down the street.
I think it was actually a Walmart Backroom. It was absolutely empty too.
