@Mark550 I believe not unless you know which guests took it and report it right away. For now, I do not think there is anything you can do to get a reimbursement since you do not know who is responsible for it. I know that cast iron is not a cheap item 😞
This is one of my biggest "homework" when I clean the entire unit that I have as well is to check the drawer where I put pots and pans, check the cups, glasses, plates, etc, to make sure that everything is in the right amount, clean, and not broken.
