this happens to me frequently.

This is perfectly normal. It happens because as the fuel goes into the tank it splashes and bubbles. As the tank gets closer to being full, the displacement caused by the bubbles forces the gas to go up the pipe that feeds the tank and triggers the "full" switch on the pump nozzle. This is similar to if you are filling up a cup of cola at a restaurant, you have to wait for the fizz to die down before you can put that last 1/4 in.
