Dear JOHN MICHEL,
Thank you for honoring my recommendations about putting in a new air conditioner within the office premises. This has made working in the office a much comfortable experience than before and everyone is happy. I am just proud to be a part of a firm that takes such suggestions up and looks after the well-being of its employees.
