I do not like the way of communication by the owner. I forgot to turn off some lights during night, then the owner claimed me for the unnecessary cost by shouting “You are bad! You are bad! You are bad!”. Since it was clearly my fault, I accepted it.
And one day hot water was gone suddenly during taking a shower. I managed to take shower by cold water, then advised the owner to check the water heating system when I did checkout. The owner got upset and said just “it’s not my fault! My family also get the trouble!!” If I were the owner, I would say just sorry for the inconvenience and explain the possible trouble before hand…
