Yes it's just two crew operation left and right hand seat. The third guy sitting on the jump seat (somewhere in the middle) keeps an eye on the other two in.case they go to sleep and wacks them if they do (unless he's asleep as well!!!!!). If they all asleep well....maybe after 20 or 30 minutes (depending on airline sop) one of the cabin staff will call and check up on them...maybe if they not fatigued or busy.
