Do I have to buy their equipment to join the tea shop?

Under normal circumstances, there is a contract. If the cooperation treaty in the contract requires the franchisee to buy the equipment of the equipment brand, then the franchisee needs to implement the contract. If there is no requirement, it can buy it by itself.

But now most tea shops will give away some equipment when they join, and the rest need to be paid, but if they buy all of them, they will not enjoy this gift discount.

Another point is that many times the products of some tea shops are unique, and the required equipment has independent standards, which may not be available in the market. If you use the equipment on the market, it is difficult to guarantee that you will make the same product. This is actually a characteristic and patent protection behavior.
