I feel certain they all knew what was going to happen and prepared accordingly.
I live within 10 miles of at least three In n Out locations. Love their food. But they aren't Whataburger, it's right down the street as well. I go to Whataburger more often, but In n Out makes a damn good burger - and the fries. They just don't have Whataburger ketchup, which is a problem.
