I used it in Indian hotels. Sure, one should get 30 day practical course on how to use bidet spray without wetting the whole restroom, without spraying junk around. If that is what initiation is, it is a failure in my considered opinion.
How does one get initiated? They had the hand sprayers at my office in India. I never tried. Experimenting with that and having to go back to work seemed like a bad idea. I also didn’t feel like asking co-workers how to use their toilets.
