That's... really poor quality trashtalk. I'm offended by the lack of creativity. At least call the manager a "vicious self proclaimed jizz hose" or something.
I don't think it's trash talk. I think it's more the developer acknowledging Harem Hotel's existence in the form of an Easter Egg that fits into dialogue. Obviously from the outside Harem Hotel looks kinda creepy. And any real person who stayed in the Hotel would probably react the same way.
