From what I've read from host/hostess club interviews, a lot of the customers for both are actually in the industry. It's like how a group of people will just pass around the same $20 on Venmo except sadder. Man actually though this entire series is kind of making me a little sad after the laughs and gags. I didn't feel as sad when watching the anime! It's just the manga that's doing it! So I hope that there are more chapters soon! Eventually!
