He wrote on his application that he can't work Sunday because "Sundays are for the Lord." He sounds like either someone extremely irony poisoned or like a homeschool Christian kid.
Not only will he have to work with me. This is a job that will make him question the existence of a benevolent God. :agony-immense:
That's a bad sign, but there's an outside chance he'll be vaguely normal. Plenty of Quakers/Methodists and Jews and Left-Catholics who won't work Saturday/Sunday and are fine people.
Though they probably wouldn't use that cringe wording.
