Ass salaamu aalykum Maw!

Ok i only can think of one sunnah for that, and that is to start from the right hand side,

Narrated Anas bin Malik:

Milk mixed with water was brought to Allah's Apostle while a bedouin was on his right and Abu Bakr was on his left. He drank (of it) and then gave (it) to the bedouin and said, 'The right" "The right (first)."

Narrated Sahl bin Sad:

Allah's Apostle was offered something to drink. He drank of it while on his right was a boy and on his left were some elderly people. He said to the boy, "May I give these (elderly) people first?" The boy said, "By Allah, O Allah's Apostle! I will not give up my share from you to somebody else." On that Allah's Apostle placed the cup in the hand of that boy.

wa alaykum ass salaam
