When the Red Bull crew arrived at the Duel, I walked over to them to tell them they could park closer to the main doors of the venue. As I approached the car, two Red Bull reps were stuffing their backpacks with Red Bull to distribute inside.
I turned around and literally saw a hoard of roboteers descending upon the Red Bull folks. I turned back to them and said "I don't think you will need to fill up your backpacks." I then proceeded to get out of the way of the throng of people as they swarmed over them.
The reps said they had plenty of free Red Bull. I hope they were right.
