Imagine some invaders confiscate your merch and give it claim tags to return it to you later. Would you believe that? I would have my doubts ever seeing it again. And even if it is returned I lose precious sell time, as my shop is closed. (Okay, the locals can't buy nor go anywhere else and buy stuff later on, but I lose out on all possible clients, that can't come from out of town.) I wouldn't stay calm.
