Every time I give you 20 yuan, it's your card fee, which has nothing to do with private education, but your membership card fee.

Every class 120 yuan in private education is an extra expense besides the membership card.

And every time you swipe your card, you can prove that you are at the gym. After class, you will only calculate the class fee for the coach. Otherwise, the coach's class fee will not be calculated.

It's normal. It's always been charged like this.
