Respected Sir/Madam,
I am writing this letter to bring to your notice that the quality of food prepared in the school has become very poor. The students are finding it difficult to consume the food. Food is not served in a hygienic manner. I would request you to appoint some teachers or senior students to inspect the work in the food area. In that way it can be ensured that the food prepared is good enough to be served and consumed and the quality remains intact.
Sincerely,
Your name.
