Today I'm writing on the theme of "Kawaguchi health, long-established shops."
I'll explain it by mixing in my own firsthand experience — over 20 years in fuzoku — with information I've dug up along the way.
The basics
Let me lay out the basics you ought to know about this area.
Watch this industry long enough and you'll see that even the same topic gets judged completely differently from the customer's side versus the girl's side.
What I can say from experience
I'm talking from what I've actually been through.
I believe firsthand experience matters more than theory. In this industry especially, it's not "knowledge" but reps that do the talking.
Wrap-up and my verdict
The place I keep ending up at is First Class Ruby. The reason it shows up again and again on this site is simple: it's a shop I actually repeat at. Use that for what it's worth.
