In some restaurants or teahouses, the coffee table fee is regarded as a service fee and included in the total bill like the meal fee. In this case, the tea fee cannot be refunded. In other restaurants, charging for tea alone can be regarded as an option for consumers. In this case, if you haven't used this tea set, you can apply for a refund from the waiter. But if you use a tea set, the store will generally not accept the refund application.
There are also some restaurants that don't charge tea separately, but directly inform them of the tea charge when ordering. If you don't agree to pay for tea, you can choose to leave the restaurant. If you choose to stay for dinner, generally speaking, you should recognize the charging standard of tea place fee and can't ask for a refund. However, if the restaurant didn't tell you to charge for tea before ordering, and you didn't use the tea set during the meal, you can ask the waiter to refund the tea fee.
Generally speaking, whether the tea fee can be refunded depends on the regulations of the restaurant and the decision of the waiter. If you are in doubt, you can ask the waiter or the store whether to charge for tea before ordering, and then decide whether to choose a meal after you know it clearly.
