The galley, being the area where food is prepared and stored, also requires regular cleaning to prevent contamination and maintain food safety standards. The lavatory is another critical area that needs attention, as it is used frequently and can quickly become unsanitary.

By including all three areas, the answer underscores the comprehensive nature of flight attendants' responsibilities when it comes to cabin service and hygiene. Proper cleaning practices in these areas contribute significantly to passenger satisfaction and overall flight safety.
