4. Dear Mr. Principal, I am a senior student of our school. I’d like to say something about the canteen service in our school. In general, the service is satisfactory. The hall is clean and tidy. The dishes look inviting and taste delicious as well. What’s more, the workers there treat us as their friends, which makes us feel very happy.

5. However, we feel the price of the meals is a little too high, besides, we can only have a limited variety of dishes with little change every week. In addition, we often have to stand in line for a long time before we can get the meal. You could understand how precious time is to us students. Therefore, may I suggest something be done to solve the problems so that we can all enjoy our meal at school? Thanks for your consideration. Sincerely Li Hua
