Premise: Evan Wolfson, the founder of the modern gay marriage movement, tells the waiter he would like an iced decaf and "the usual." Wolfson, one of Time Magazine's Most Influential People in the World, is a man who unflinchingly knows what he wants and stays his course, whether it be in his choice of restaurant or in his choice of battle. And others always know when they see Evan coming what it is that he wants.
Hypothesis: Evan Wolfson was talking to someone that works at a food service establishment.
