In a grocery store, Sarah sees her friend Lisa put a box of cereal in her shopping cart before going to another aisle. While Lisa is away, an employee accidentally takes the cereal out of Lisa's cart and returns it to the shelf. Later, another customer picks up the same box of cereal and puts it in their cart. When Lisa goes to check out, what does Sarah think happened to the box of cereal? Make your response very short.
Sarah might think that the cereal was stolen or misplaced by another customer since she saw Lisa put it in her cart and now it's gone. She's unaware of the employee's involvement and the later actions of another customer. From Sarah's perspective, the cereal's disappearance is likely attributed to a typical store mishap such as theft or accidental displacement by someone else shopping.
