Formal thank you message

Good day, I would like to express my sincere gratitude to Piatto Restaurant Mall of the South and the entire staff for the wonderful surprise you arranged for my son today. After ordering our meal, we were delighted when the waiter brought a plate of ice cream to congratulate him on passing Grade 12. I was truly touched by this thoughtful gesture and deeply appreciate the kindness and warm congratulations extended to us. The waiter had overheard me telling my son that today is all about him and his achievement, which made the moment even more special. Thank you once again.
