Congrats to R/D and R/A. They were the only teams smart enough NOT to give money to M/G.
This is a competition, and you know one team is going to be eliminated at the end of this leg (esp. cause the last one was a non-elim).
They have been dealt a fatal blow, and you now hae a step up on them. Why give it away.
On this show Money = Power.
Having more money allows you to pay for quicker transportation, pay people to help you with directions, buy maps, food, etc, etc, etc.
You are also only given a finate amount for each leg. Why sacrifice some of it to another team? Even if it's just a loan, you are lowering your bankroll, and allowing them to increase theirs.
I am sure M/G could have gotten money at the airport, but why make their life easy?
