I rode Space Mountain once, and noticed that a rider in front of me was munching away on a slice of pizza - probably from Red Rocket's. He evidently had kept it concealed until we were careening down the tracks in the dark.
One has to wonder, did this person not want to take the time to dine at a restaurant? Seems like he could have gagged, or spilled his food on another rider.
Has anybody here snuck food onto a ride, or noticed somebody else who had?
