Filling Up at Gas Station--Class A Gasser

We will opt for the gas pumps at a Flying J whenever possible. We use their pamphlet and The Next Exit to help us locate one and I always start being aware about the time I hit 1/2 a tank. We have found that almost all stations that feature two sets of pumps per island have enough room to get in and out with little problem. Cars wanting to scoot in ahead of you when you are waiting for a particular pump are annoying but I have had good luck with just explaining to them that I really need THAT pump and have been waiting for it to come open. The other problem is the one who pulls in, disappears inside, comes back after 5 or 10 minutes, then starts gassing up, then of course, disappears again to go pay seemingly oblivious to the elephant on his rear bumper drumming his fingers on the steering wheel. This is when I try to tell myself that I am retired and I really don't have anywhere to be or any particular time I need to get there.
