@Frank1481 Guests often assume that any consumable items like drinks or food in an Entire Home space are available for their use, unless you set clear boundaries such as a lock on the cabinet.
Kitchen utensils that go missing are often found elsewhere in the property, so it might be better to ask the guest about them politely than to go straight to a resolution request. If you intend to keep on renting the barn, some good ratings and reviews are worth a lot more for your listing than the cost of replacing a few missing items, so in the grand scheme of things, a resolution claim may cost you more than it yields.
