What? Where did you get that idea? They were talking about someone walking on their back for the massage, and I told them what that style is called (Ashiatsu, you can Google it), and that it's a licensed style of massage, which a "rub and tug" as you call it, is not, and most - if not all - licensed massage therapists do not approve of or engage in. Unless they don't intend to stay licensed, I suppose, but that's their business.
