There was also the two smugglers (I guess) on the Merchantman in ST3. McCoy was also trying to charter a ship from Mr. Big Ears in that film. In TNG:Birthright, Worf apparently made his way to that planet on his own, which means he coerced a ride out of someone. Then there's Kivas Fajo, the 24th century equivalent of today's OCD toy collectors who think that everything they own will be worth millions someday.
