Can I just say how annoyed I am at teams complaining that the Yield option is unfair, and that anyone who does use it is scum? The Yield is a PART OF THE GAME, which if used correctly, can help teams get further in the race. Dustin and Kandice realized this, and yielded Eric and Danielle, because while Uchenna and Joyce got held back, they had no way of knowing this. As far as the BQ's were concerned, they thought they were fighting for last place, and they needed an edge.
I could maybe understand Eric and Danielle's frustration at the beginning, but there's no need to harbour a grudge. That's just petty. And, why the hell would Charla and Mirna get on their cases like that. It's not like they were yielded BY them. Yet, I bet that they'd be the first to yield the BQ's the next time a Yield option is available.
