When all this hollering and carrying on starts, Dustin sort of doesn't understand why this has escalated like this. She says, "Chill out a second. How much money are we talking about?" Mirna turns to the cab driver and says, thickly accented, "How much dollar you need?" He doesn't understand English if you use connecting words. He tells her he needs a hundred dollars. Dustin tells Mirna that rather than paying all that money, they should have the driver draw a map for them. Mirna kind of isn't tracking, and she's all, "He's not going to draw a map for you!", as if Dustin is asking to have the driver draw a free map for her, and the hell with Mirna and Charla. Dustin is obviously suggesting that on this trip, they don't need to pay a driver to lead them 70 miles on a straight highway. What they need is a map. Dustin's thinking is clearly pretty sound. But Mirna and Charla keep bitching and babbling, so finally, the BQs are like, "See ya, crazies," and they hop in their SUV and speed off. Because the difference between them and Charla and Mirna is that they don't need to follow. That's why Mirna had no bargaining power. The BQs thought the driver might be a good source of information without being paid to drive all the way to the pit stop, but they're okay going on without him. Mirna, on the other hand, is desperate to follow, because she has no confidence in her ability to navigate. In that sense, she had nothing to bargain with when she started freaking out about them following her. Dustin and Kandice were legitimately behind Charla and Mirna on the highway -- what are they to do other than follow? Was Mirna arguing their obligation was to pass? To turn around and go to the other way? What's her suggestion for them? There's only the one road, you know. When Mirna mutters about "freeloaders," it's silly, because they were actually trying to come up with a cooperative strategy that was mutually beneficial and transitory -- they were suggesting something better so that nobody had to go broke paying the driver. Of course, Mirna missed it, and decided that she was being victimized, probably because Charla is small.
