The excellence of the cleaning as it posted

The black cleaning guy in I-house never have cleaned as suffice or as at all. He is of course, causing a lot of troubles with residents. Today, I heard a British guy complaining at him when I was at stairs and found the door of a random room open. The excuse he always uses to everyone is that he has an extra apartment to clean. He always insists the excuse though, when has he built a new I-house building? I would like to see the extra building which keeps him so busy.
