A man who loves to serve

This is Marc. He came today to service my furnace and air conditioner. He said it would take about 90 minutes. During that time I baked some brownies intending to give him some. By the time he was done, the brownies were not. Marc said I was his last customer of the day and he could stay another 30 minutes to fix some minor things while the brownies finished. Well minor turned to major and he was here for another 90 minutes. My bill did not change, nor did his smile. I finally talked him into closing up the furnace and going home with a plate of brownies.
