““At Hamilton Brothers, not much is self-serve, and I was forced to interact with the guys at the counter. These were all middle-aged men who evidently knew a lot about everything. They would ask me questions about my order that I often couldn't answer. “What size chickenwire?" or “Ardox nails or regular?" or the one that always struck me with fear, “What you doing with all this stuff?" It seemed they were running my order through a vast mental database and determining that there was nothing known to humanity that could be built properly with the list of items I wanted.””
