Yes I don't know what could be the reason why he does that, But based on what's the content said, I must say that he must use the money wise. Maybe he should donate those on charity, fund for nature development, or for elders and homeless.

I should tell him that abusing what you have would leads to a bad outcome not on people, but it begins to the people who have a crab mentality that was called karma. For the siren in PH only cops and ambulance is allowed to use for that. Siren was made for emergency rush purposes. We don't waste money for nonsense things. If you are in the room which cost lots of thousands, then have he ever think about people who sleep in cold streets?
