Debtor giving the creditor a gift

Q: I am a dentist. I did a consult for a patient and arranged specialist referral. I did not charge him for the consult. He was referred back for treatment which I carried out at half price. Thereafter, he asked for a few days to arrange the money. A week later, he then gave me a gift of honey. The day after he gave me the honey, he paid his account in full. Is the gift of honey riba, as at that time, he owed me money?
