Dear Headmaster,

I am writing to talk about the canteen of our school. There are only a few stand in the canteen, leading to lots of students have to line up for food. It is waste of time, isn’t it? But at times the food is not fresh and does not taste deliciously. So it’s not surprising that some students chose to go to the street to buy junk food which do harm to their health. Would you think about that how to improve it? I would appreciate you if you could take some measures. Hopefully, my opinion can be taken to account.

Jack
