Alan is a customer at a Target store Pizza Hut in "Island Adventure".
While an oblivious Lois checks out with wine and a t-shirt, Stewie, working as a cashier at the snack bar, announces that Alan's sausage and pepperoni pizza is ready. When Alan arrives to pick it up, he notes that he only ordered pepperoni. After checking his receipt, Stewie rings up the corrected order.
