Final answer:
The best response by the sales associate is to offer an appointment with the custom drapery department to accommodate the non-standard window sizes, with a reminder that precise measurements including units are crucial.
Step-by-step explanation:
The sales associate's best response would be: "I can make an appointment with our custom drapery department if you like." This shows a proactive approach to solving the customer’s issue and provides a personalized service.
Additionally, it’s essential for the customer to provide exact measurements, including the units of measurement, for the custom curtains.
Without specifying whether the dimensions are in inches, centimeters, or meters, the custom drapery department cannot accurately fulfill the customer's needs.
For example, if making curtains for a house, the customer might need fabric that is 2 meters wide and 6 meters long. Conversely, if these were for a doll's house, the measurements might be 2 centimeters wide and 6 centimeters long!
