Dear principal,
I'm regret to write this letter to you.I would like to suggest some issues about our canteen.
There are many kinds of food in our canteen,and the food is cheap,that's the point we would like to have the meal in the canteen.
Also I want to suggest is that the staffs who are working for canteen serve badly.They just got negative attitudes to serve us.And we always spend so much time on waiting for our meal ready.That's wasting our valuable time.The most important thing is the bad taste of the food in canteen.We can't stand any more.
We'll appreciate if you can make some changes in our canteen.Thank you for your time.
Yours sincerely
