I'll make a list of fitness clubs for you, in descending order: member consultant (sales consultant), member supervisor (sales supervisor), member manager (sales manager), store manager (one store is in charge of everything), sales director (several stores are in charge of everything) and boss. The manager's duty is TO be responsible for the sales of fitness cards. One of the most important functions is that the salesman encounters obstacles in the sales process (mainly because the price customers can't accept it), and the manager to (high-level intervention to reduce the price for various reasons) assists in the transaction. If you enter the TO stage, under normal circumstances, customers can't run away, which is unique as long as the managers are strong enough.
