Aaron and Shauna are a couple that Stewie and his Ukrainian bride Zlata dine out with at Macaroni Grill in "The Marrying Kind".
As he tries to steer Zolata towards a lower-priced entree on the menu, Stewie relates a story from his work at Enterprise Rent-A-Car. When the check arrives, he pays only for his and Zlata's meals and directs the remainder to Aaron and Shauna.
