As this stunt actually happened, I seriously contemplated going to that box. Yep. A box, where I'd save another person by taking their seat in the box. The thing that stopped me? I have offspring that need picking up from school, and doubted that I would be let out on time. The turnaround was often a lot quicker than I suspected it would be, which is rather surprising.
Good luck in Cannes with this one, guys.
