Final answer:
In a situation where demand exceeds supply for air conditioners, the seller should communicate stock limitations upfront, consider offering the product on a first-come-first-served basis or via a fair random draw, and explore alternative solutions such as rain checks or discounted alternatives.
Step-by-step explanation:
When faced with the dilemma of having only one air conditioner in stock while two customers want to purchase it, the best approach is to handle the situation transparently and ethically. Firstly, communicate honestly about the stock limitations to both customers. If a first-come-first-served policy was not previously communicated, you could offer the product to the first customer who showed interest, or if both discovered the product simultaneously, conduct a fair selection method, such as a random draw. Additionally, consider offering the second customer a rain check for the item at the sale price, or inform them when new stock is expected. Alternatively, if you have an equivalent or superior model available, offer it to the second customer at a comparable discount. Lastly, ensure to provide excellent customer service throughout the interaction to maintain goodwill and a positive reputation for the store.
