Leading the way from baggage pickup

Scene at the airport baggage claim after Allison picked up her parents:
Allison: Now off to the parking lot.  It's easiest to take the elevator upstairs.  Follow me.
Fran (Allison's mom): But that sign says we have to take the escalators downstairs.
Allison: I live here.  Follow me.
(the three of them take the elevator upstairs, then follow directions to parking, taking the escalators downstairs and ending right where they started).
