I just didn't understood what this of the Briefcases was all about. So ok, they want us to believe that they were carrying the $50,000 with them all the time but....
They screwed somehow.
On the final episode, Tyler get both briefcase for the final teams and place them on the floor, first he grabs the Middle Feast on and place it next to he (To his right) then he grabs the Texans one and place it to the right of it.
After counting all the money and when he is ready to announce the winner, he grabs the very right briefcase (left on the screen) that was the briefcase that the Texans gave him, but when he opens it, the paper inside had the name of The Middle Feast Truck.
I don't understand. They clearly did something weird in there.
