i think whoever packs the bowl either gets greens, or chooses who gets greens, and they choose where to pass it. but usually im smoking with friends....and with my old school chiefin buddies we never have like set rotations and shit, we try to all get greens evenly no matter who packed it. i always get my first greens when i pack, but i always give the next greens to whoever wants it first. oh, the only time i ever use a set rotation is if someone is matching me a bowl, then they get tuesdays, and when they pack their bowl up, they get mondays and i get tuesdays, thne it goes from there
