Seems as though "short visits excluded" raises a lot of questions -- does that mean that a place that does mostly drive thru business (say, Jack in the box) might still be serving more customers than a primarily sit-down place (Panera, chick-fil-A)? Also, at least where I live, In n Out has horrendously long wait times in their drive thru, where as others are much faster, sonmaybe their sit down and their drive through visits count as "long"?
