In "Creepy Connie 3: The Creepening", the store Emma works at gets robbed under her watch and she, Zuri, and Bertram are able to use their knowledge of the fancy restaurants they've been to by using what's left (lettuce, ketchup, and a potato chip) to satisfy the customers, and it worked. Even though Emma got fired, she got her job back after learning Emma sold them for 11 dollars each.
