For several years now, I have thought of waiting tables as a hunter-gatherer kind of job. Each morning, I stalk my prey at their usual watering hole, serving up coffee and eggs with a sleek and casual smile; I am quiet, unobtrusive; I bide my time. My earnings are gifts from the gods of generosity and good luck, coming in unpredictable floods and trickles. I gather the silvery coins from the tabletops, I fold the bills into my apron pocket, and I move on again, cleaning, preparing for the breakfast rush, the lunch rush, the next herd to come and go. I'm no agriculturalist.
