Yes, Serendipidy, it is unfortunately accepted.
Remember, in the chain studios, you pay for the steps you learn... trust me, I go to one myself. Yes, you are paying per hour, but you are only allowed to be taught certain syllabus steps in the program you have paid for. Hence, you can take someone with no dance experience, teach them those few steps, and make them teach it to beginners.
My friend was paired with a new "instructor" at the studio I attend. She has been taking lessons for a year, and has paid a total of $7,500 so far. After her lesson, this "instructor" was pulled aside by another instructor and was told that he was not doing the underarm turn in the waltz correctly! Even my friend noticed he was doing something wrong. Go figure.
