Go to the hotel for tea.

If guests return to the hotel after buying tea and find that some tea leaves are moldy, they can take the following steps to solve the problem:

1.** Stay calm * *: It is very important to stay calm under any circumstances. If guests are not satisfied with the quality of tea, they should keep calm and take appropriate measures to solve the problem.

2.** Check the purchase voucher * *: Guests should check their purchase vouchers, such as receipts or shopping receipts, to confirm that they have actually purchased this kind of tea. If they don't have these vouchers, they should contact the merchants as soon as possible to ask for them.

3.** Contact the merchant * *: Once the customer confirms his purchase voucher, he should contact the merchant as soon as possible to explain that the tea leaves are moldy and ask for a return. Guests should be polite and patient when contacting merchants, and provide detailed information as much as possible, so that merchants can better understand the seriousness of the problem.

4.** Provide evidence * *: Guests can shoot or take photos of moldy tea leaves and send them to the merchants as evidence. This will help to prove that there are indeed quality problems in tea.

5.** Waiting for the solution * *: The guest should wait for the solution from the merchant. Possible solutions include refund, tea replacement or other compensation measures. If the guest is not satisfied with the solution of the merchant, he can seek further help.

6.** Complain to the consumer protection agency * *: If the merchant can't solve the problem or the rights and interests of the guests are infringed, the guests can complain to the local consumer protection agency. When a guest complains, he should try to provide evidence and explain the problem in detail.

In short, if guests return to the hotel after buying tea and find that some tea leaves are moldy, they can take the above steps to solve the problem. At the same time, guests should also pay attention to safeguarding their rights and interests, and be patient and polite in solving problems.
