I've been checking, esp. since I saw the coverage about this very thing on cable news this very week. They piece had the Texas State Commissioner on talking about how this problem is on the increase... in Texas, it is up 30% for complaints against service stations. He said, if we find this happening to us, to report it to the State Department of Agriculture. This bit of info wasn't in the email I received. So, it is happening, at least in Texas.
