Hi!!!
At our airline, the primary role is quite obvious, we are there for safety, although service etc plays a huge part as we then wouldn't have an airline if it wasn't good, but that is the main reason we're there. As you have, we have day to day duties and service standards etc, but thats only because emergencies don't happen to us every duty thank goodness, so if we were there only to do what we're really there for, safety in dealing with evacuations etc, then our jobs would be pretty boring as we'd be sitting around doing nothing.
