I think the explanation is rational. Whoever causes the problem should indeed be the party to pay for the damages, even if they occur outside of their own premises. I think it is just fair. The same rule applies to our self-storage in Blue Mountains. If there are any damages to our customers’ belongings inside their units, we investigate the root of the problem. If it is a leakage from outside for example, we will compensate them back the full costs. However, if the customers’ belongings damage our property, they will be liable in that case.
