Let's talk about the boss's wife first Just like you said, at first she did everything you said, and then she changed her face when you paid. You can blow up her bullshit coach. Always changing coaches, always advertising to those garbage coaches.
Once upon a time, there was a belly dance instructor. It turned out that the coach made their yoga studio popular. The proprietress insisted that she was popular. Later, the coach went out by himself and opened a ballroom next to Tesco, killing the yoga business. The proprietress always tells the members that the coach has no personality and no professional ethics. I don't know who is morally corrupt!
That proprietress is as fat as a pig, always comparing herself with the members there, thinking that she has a good figure and is self-righteous.
I have a friend who hasn't lost weight after practicing yoga for several months. I went to another yoga club, and I didn't recognize the weight loss after a summer vacation.
There are still many places where yoga bosses and proprietress are dishonest, so I won't say it.
In short, it is better not to go to that place.
I suggest you don't go to Tai Yoga, you will regret it. If you pay the money, you can't get it back. You can only waste money!
