How about Rongmeier hotpot? Does it taste good?

Hot pot is average, and the waiter's attitude is very poor. Last time I printed a hot pot buffet coupon for 19.9 yuan in tintin network, when I went to his house for dinner, the waiter accepted 20 yuan. I asked why it wasn't 19.9 yuan. The waiter had a bad attitude and said it was 20 yuan. That's how our family resumed land. Although I only charged ten cents more, I was very angry. I don't think it's a dime problem, but a honesty problem. Since there is no integrity in doing business, what price should we bid? The waiter's attitude is still so bad, so arrogant, so irritating, and he will never eat again!
