I need to comment with a disclaimer: I Love In-N-Out. Every time I go to California or Vegas, I go to In-N-Out.
But they are, in reality, a secretitive, family-owned, Christofascist, fundamentalist business who underpays their employees, fires people for taking a day off work for an emergency (California passed a law forbidding this, but they still do it). They recently announced their going to open a store in Nashville (or as I call it, NashVegas). It's a matter of time before they're nationwide. Like Coors 40 years ago. Or Chick-Fil-A.
