If you knew Brooke you would know for sure she just didn't reorder them when she ran out. She is the only one in the branch. And it's her responsibility as the postmaster of the branch to reorder them. In rural branches of this size there are no "clerks" just the postmaster. This happened prior to "peak" season. With all the people that work from home or have ebay stores postal money orders are essential to their business. Money orders are not the same as cash. You can't take one addressed to gunbunny to walmart and buy a case of beer. You can take any 50 dollar bill and buy one. She only became "accountable" when complaints were filed above her head. It may be different where you live.
