Ha ha...mdarmistead...reading your posts is almost exactly what I experience with my wife at the end of every tank. I told her that because we fill it every 18 days, she forgets that we've had the exact same conversation before.

Once we were in a major traffic jam in Philadelphia where Homeland Security shut down one of the 2 bridges to NJ. We had 1 gas pip left, but when that baby disappeared I thought she was going to hyperventilate. We were in that mess for over an hour and we still had more than 2 gallons left when we finally filled up, which she insisted that we do right away.

I've finally convinced her that there is nothing to worry about. The most I've ever had to put in was 11 gallons.

Unfortunately, it will take you several tanks to finally convince her. Good luck.
