The poor dear. She can't find her car. She needed to grab the reminder slip. She doesn't know if she parked in Green, Gold, Blue, and on which level. From the size of that suitcase, she probably doesn't want to schlep it around the parking garage. Lesson to those who use the Lindbergh Terminal to park your car.
My tip: park over at Humphrey Terminal and take the free Lightrail over to Lindbergh.
If you can't find your car, this may as well be Wonka's Golden Ticket. I grabbed a few extra as a joke to put on friend's cars who always can't remember where they've parked.
