"I had a bad experience when I went to your restaurant yesterday. It is normal to tip the waiters in a restaurant, but how much to tip is up to the guests themselves, not for the waiters in your restaurant to come and ask the guests for the 18% service charge. If your restaurant really has such a rule, it should be marked at the door or on the menu that there will be an 18% service charge. If there is no mark, today the waiter said 18%, and next time I came, another waiter said 20%. Will it become 25% in half a year? Anyway, the amount is up to your waiters to say. In this case, I dare not go to your house for dinner with my friends and my family in the future. No matter how good the food in your restaurant is, it can't beat the waiters who charge exorbitant tips."
