Should one start with the right, even if there is an elder and a scholar in the gathering?

Question:
If there is an elder in age, a scholar, and a memorizer in the gathering, with whom does one start?

Answer:
One starts with the person on his right. If he drinks, he gives to the person on his right, even if the person on his right is a layman... unless he gives permission.
Q: Does one start with the elder or the scholar?
A: One starts with the person on his right.
Q: When one first enters the gathering, does he start with the person on his right immediately, or does he start with the elders?
A: No, he starts with the head of the gathering, and then the head of the gathering directs him to the right.
