Heidi is a German waitress at the Double R Diner, who is often late to work, saying she "could not get her car started" so she had to "jump start the old man."
Heidi showed up to work late on February 24, 1989, claiming she could not get her car started, so Shelly Johnson finished the thought with "too busy jump-starting the old man, huh?" Heidi giggled as Bobby Briggs says "I thought you Germans were always on time." She giggled again, all the way back to the kitchen.
Roughly a month later, she came into work late again, seeing Bobby and Shelly teasing each other. Heidi claimed she could not get her car started, so Shelly finished the thought with "too busy jump-starting the old man again." She giggled all the way to the kitchen.
Heidi still worked at the diner 25 years later and had become acquainted with customer Miriam Sullivan, who one day left a tip that Heidi and Shelly agreed she could not afford. As a token of appreciation for Miriam, the waitresses plan to treat her.
