Maybe it is just me, but it seems like the tanks I get when I swap out an empty for a new tank aren't as full as they used to be. I used to get one tank and it would last through the summer; I am now on my third tank of the summer. My grilling habits haven't changed and my grill doesn't have any leaks. The service is convenient, but I am not sure the tanks are being filled to their full potential.
Not really a true complaint; more like an aggravation.
