Reference for Pesachim 156:14

אכתי דילמא שאני התם דאי ממשכי הני חזי להו א"כ ליתני הואיל וראויים לימשך מאי שכבר נזרק הדם ש"מ בדם תליא מילתא אבל אכילה לא מעכבא

- Rather it is this [dictum of] R'Nathan. For it was taught: If one company registered for it, and then another company registered for it, the former, for whom there is as much as an olive [per person], eat it and are exempt from sacrificing a second Passover-offering; the latter, for whom there is not as much as an olive [per person], cannot eat, and they are bound to sacrifice a second Passover-offering.
