The tall guy ate a particularly small piece of cake, and drank a cup of coffee. He came into the eating establishment every day just before the sun rose, and constantly ordered the same thing. He did not seem to appreciate the slice of cake, but he always ate the entire thing. He liked to sit quietly there, alone, for about an hour and then thank the waitress and leave. After a few nights of this, the staff got used to him. No a single even minded that he didn’t tip. He constantly sat in the same exact booth, just underneath the central air vent. Every day he entered sweaty, then sat and quietly soaked up that beautiful air conditioning as he ate his piece of cake and slowly drank his coffee. After a few weeks, all the people figured out that he wasn’t coming for the food in the diner, just for the a/c. As sizzling as it had been that year, who could blame him for wanting adequate cooling. One day he came into the diner for his piece of cake and found that the Heating and A/C had broken down, and the eating establishment was in fact stifling hot. He sat in the same locale, ate his cake, and calmly watched as the A/C contractor inspected the system. The central Heating and A/C component was in nice shape, and it seemed that all the ductwork just so happened to be clear and properly sealed. Finally the tall guy spoke up, and asked if the repairman had gone ahead and actually checked the eating establishment’s temperature control. It turns out the tall guy had been an expert Heating and A/C repair specialist for many years, but simply didn’t want air conditioning installed for a hefty price in his home.
