A flight attendant has decided to be a toilet paper roll racing team of one as he walks up the aisle.
At least I’m going to assume that the flight attendant did this willingly and wasn’t the victim of a joke by other members of the crew. Passengers, definitely don’t try this inflight because you don’t know how your crewmember will take it, and you could find law enforcement waiting for you when you land (if they can figure out who the perpetrator was among a plane full of passengers).
