When I was younger, I had a job at a fast food diner. For more than nine years, I spent various mornings in that store. I was General Manager & it was our job to make sure everything was ship shape at night. I had to do the inventory & get the payroll around. I was just on our way out of the diner a single night, when I heard an odd noise. I knew I couldn’t leave if there was a problem. I tracked down where the sound was coming from & I found out I had a leak in our moderate water system, however i called the plumber, but I also called the Heating as well as A/C supplier. I was afraid that all of the water was going to put out the pilot light on our furnace. No sooner had the plumber showed up, but our Heating as well as A/C specialist was also there. I had both men down in the basement going over the furnace & the moderate water heater. They had only been there for half an hour & the plumber had his water leak fixed. The Heating as well as A/C specialist came up & told me I had made a wise choice in calling him. There was a concern with the furnace, & it had nothing to do with the water leak. Had I not called him when I did, every one of us would have come in to no heat & the entire place would have been frozen. The temperature was going down to 10 degrees that night. I waited in the store for another hour, while he made the repair to the furnace.
