Well, there was one fern I absolutely hated... it was the lady the father and (lesbian) daughter met on the plane to hanoi in season 10. she told them she could take them around town. she was such a memorably hateful fern
First she made them wait for her at the airport, then she told the taxi driver to take her to her house first to get her brother somewhere. Such a freeloader, that fern, she actually wanted to get a free ride for her (and later her brother)! She was also very rude
"Do you not understand what I saying?"
and not remorseful at all for telling the racers half-truths throughout.
By the time they wisened up to throw the fern out of the taxi, the additional distance travelled to said fern's house had cost them their money and they only got to their next clue by the grace of their taxi driver who accepted $11 as payment. That was also the start of the bad luck that team had throughout the leg and eventually they came in last. foreshadowing much? I don't know but not all ferns are helpful and fans of the show, some just want to piss racers off and get screen time. And in this case, a free ride.
BEEYOTCH!
