Real simple, folks. It's called "Care, Custody and Control". That basically means they are responsible, no matter what kind of written or implied disclaimer they try to hide behind. You would not leave an item if you knew it was going to be damaged or stolen. They would not have any customers if everyone knew their items would be damaged or stolen. So, by the very fact that they allowed you to leave your property, they implied a reasonable level of security. If they could not provide adequate security, they should have told you not to leave your property or provided a higher level of security. Yes, they do have responsibility for your property!
