Why are Mormons studying coffee machines at BYU?

Not knowing the situation, I cannot be as "judgmental" of the student as you appear to be. There could be a variety of reasons, including using it as a heating device for hot water for "Cup-o-Noodles" or something of the sort. Or, you could be nonjudgmental and believe a person at their word. Perhaps this says more about you and the student.
