I worked in multiple stores across multiple years - they don't just lean Christian. The stores, the owners, and most management are deeply religious in my experience. I was pressured to go to Dave Ramsey classes, go to church, pray at every meeting, etc.

Not saying it is an evil place, most of the people I worked with were the kind to practice what they preach and aren't hateful people. But don't fool yourself into thinking the individual restaurants aren't as religious as the brand as a whole.
