I have had this issue with mine too. When this happens to me, I normally have the nozzle inserted all the way in and I simply pull it out about a half inch or so. It doesn't happen at all gas stations so I'm guessing it has something to due with the curvature of the nozzle. Might be worth a shot if you haven't tried this already.
