Freeman Makes the Deal

Though Rom and Leeta were always more than on board with signing an agreement with Starfleet, they're still very much the Ferengi's ruling couple and wanted to put the Cerritos crew through the wringer during the negotiations to make sure they're not "a bunch of suckers and rubes" and they respect their culture. As soon as Freeman shows off some shiftiness of her own in their agreement, they are more than willing to drop their initial difficulties with the negotiations and immediately sign off on the original papers.
