Answer:
You attempt to procure the item (if within your ability); otherwise, inform the guest that you are unable to obtain the item.
Explanation:
In order to please your customer, you need to satisfy their request. If their request is within your ability to fulfill the obligation, then inform them you will comply with their requests and attempt to procure the item. If you are unable to satisfy their request, inform the guest that you cannot obtain the item and perhaps help them by showing them how or where they can obtain the item.
Cheers.
