Ruling on starting with the person on the right if he is young

Question:
If the person on his right is younger and the person on his left is older?

Answer:
He should ask for permission or give to the person on his right, even if he is younger, just as the Prophet (peace and blessings be upon him) gave to Ibn Abbas and left the elders, unless the younger one gives permission to the person on his right to give to the person on his left, in which case there is no harm.
Q: In the gathering, does one start with the elder or the person on the right when entering with the tray or the tea?
The Shaykh: The head of the gathering and the elder of the gathering, one starts with the elder, then the person on his right.
