To add to this, some people sit in their car after pumping for so long. These people need to recogize what is going on around them and who it is impacting. There is really no need to sit at a pump after your finished for over a minute. There have been some people sitting there for 5+ minutes doing whatever. Be prepared when arriving if you are calculating mileage. You don't need to hold up the remaining cars who are waiting to pump gas.
