Dear Chetna,
On behalf of all RAF aircrew who you so diligently looked after, I just wanted to say thank you for working so tirelessly to provide an awesome service even though you had to singlehandedly shut down the clinic and treat patients at the same time. Your dedication and commitment to your patients was noteworthy, and I wish you all the happiness in your future employment. You will be missed by many.
warmest thanks
DH
