Joanne and Peri go to the restroom while Ray goes inside the store to get Joanne a drink and Peri some batteries.
When the girls return back to the car, Peri is worried as she cannot find her compact which she believes she took inside the restroom with her.
Joanne goes back inside to check for it.
Then Peri steps outside the car while Ray checks the backseat.
