I'm confused. If a tenant smelled gas (like from an appliance) they were correct in contacting the gas company because it is a free service they offer. He puts his sniffer behind the appliance and the machine lights up, indicating there is in fact a gas leak. So instead of helping the customer out and correcting the problem (most likely a loosened gas fitting), he shuts down all gas from the meter? That is bad customer service, plain and simple.
Just two days ago, my wife smelled gas in our kitchen and I instructed her to call the gas company, because I was too busy to come home to help. Within two hours, the service man was at my door, put his sniffer to use, and found a loose fitting below our oven. He coated the threads with Rectorseal # 5, and tightened it up. Problem was done, but he wasn't. He inspected my oven, found a loose thermostat, replaced it, and went on to inspect all my appliances, making certain all the fittings were leak free.
That my friends, is what customer service is all about! And before you can ask me, I already have a nice thank you letter (attaboy letter) which we will be sending to our gas company!
