Sandi Karrmann, identified as the Chief People Officer for the worldwide chain, wrote: "Dear Deacon, we recently heard that you want to be a pizza delivery driver when you grow up. How wonderful! You've got several years to go before you can join our team, but in the meantime we're sending you a few things, so that you can practice."
The company's gifts to Deacon include a specially tailored Pizza Hut uniform, a mini delivery car and gift cards for pizzas.
Karrmann signed off the letter with some words of encouragement for the little boy.
She wrote: "We have delivery drivers who have worked for us for 10, 15, even 20 years! And the same Pizza Hut drivers who deliver hot, fresh pizzas right to your door have gone on to become successful businessmen, doctors, lawyers and, yes, actors.
"Deacon, keep on dreaming big and know that we're saving a spot for you on our team."
