Perhaps its because I only know the basic facts about hosts and hostesses. I mean I have never been to any of those types of bars and I don't know any hostesses on a deep enough level to ask them about what working life means for them.
I hosting and hostessing is not glamorous, it can be unsafe (not just in crazy stalker follows you and stabs you, as in you don't have job security) and it takes a physical toll on the workers. But it still attracts many people as both workers and customers.
One thing I find interesting is how all host clubs belong to a "group", which generally owns/manages several host clubs. Whenever I see the group name under the club name I get the feeling like its a cult or a mafia haha! But host clubs are businesses, which are very carefully managed in styling, image and service to get you to part with your money.
There are a wide variety of clubs to choose from, and sometimes I wonder how so many can keep making money as they do. Well I know hostess clubs are not doing as well as they had some years ago. But despite the difficult financial times, paying someone for a fake relationship continues in Japan^^
Sorry I don't have much more to say on the topic. There are plenty of websites that explain what hosts and hostesses are, so it's unnecessary for me to reiterate. I never plan to go to one myself as my money is more important than fake flirting with some overly-done guy. So I'll never be the one to give a first hand account.
