How can we prevent hotel guests from leaving things behind?

Even if there is a warm reminder in the room, it's the same. It's inevitable to forget it or not. When you check out, you will be prompted verbally, and you won't forget the important items, so it won't waste any time. Generally, regular hotels will notify the room attendant to check the room when you check out, and make rounds within 3 minutes. You can check the left-behind items and damaged or taken items, feedback them to the front desk in time, and ask if they are still needed. In addition, it is best to establish a registration of left-behind items.
