Final answer:
The salesperson should explain the promotion's terms to the customer and offer alternatives to help them qualify for the free toiletry set, while ensuring good customer service.
Step-by-step explanation:
If a customer spends a little less than the required $75.00 but still requests the free toiletry set worth $50.00, the best course of action for the salesperson is to politely explain the promotion's terms and offer alternatives to the customer. These alternatives could include suggesting additional items to purchase that would bring the total up to the required amount or explaining any other promotions that might apply. Nonetheless, the salesperson should maintain a balance between upholding the store's policies and providing excellent customer service to ensure a positive shopping experience.
