Are you guys working for Google or Amazon or so? Maybe I should give something simple analogy so you understand.
If your neighbours washing machine breaks down, and causes you water damage. They have to pay for cleaning up de mess they created in your apartment. If the neighbour spills oil on your parkway, they have to clean it up. Your reasoning resembles: - the neighbour does have to use their washing machine every time, so I will just clean up their mess every time. - it is only once of every 3 times the neighbour uses his washing machine, he floods my apartment, so that is ok. - the neighbour has kids, they cannot be held responsible for dad to flood my apartment every week. So I will not ask the landlord to evict them. I will just clean up their mess every week year after year. - the neighbour floods my apartment every week, I think I will teach him this week how to use the washing machine. - the neighbour floods my apartment every week, I think I will replace my wooden floor for some plastic foil.
