A hot water heater

When I was younger, I had a job at a fast food restaurant.  For various years, I spent various nights in that store. I was General Manager & it was my job to make sure everything was ship shape at night.  I had to do the inventory & get the payroll around. I was just on my way out of the restaurant 1 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 water system, and i called the plumber, although I also called the Heating, Ventilation, & A/C business.  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, Ventilation, & A/C worker was also there. I had both women down in the basement going over the furnace & the hot water heater.  They had only been there for half an hour & the plumber had her water leak fixed. The Heating, Ventilation, & A/C worker came up & told myself and others I had made a wise choice in calling him. There was a problem 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 venue would have been frozen. The temperature was going down to 10 degrees that night. I waited in the store for another hour, while she made the service to the furnace.
