I believe the reason Mr. Stopnick chose to say he lost the 20 dollars is because he genuinely cared for Noah and probably did not want the problem to escalade any further. The tensions were already high between Noah and Caroline, and if Rose were to bring up the 20 dollar bill situation, Caroline may still had been angry about it thus leading to further problems. I believe the intentions of Mr. Stopnick were to defuse the situation by any means and hope for a quick solution.
