Something just doesn't ring true with this.
Someone flops out their meat and starts beating it next to me in the confined quarters of an airplane, and there's pretty much immediately gonna be a fist fight in progress.
He sure as heck ain't gonna have the time to get "it" off before most of the rest of the plane is well aware something is going on.
She didn't call out, scream, or smack him in the head at any point in the procedure... Just doesn't seem like what would happen to me.
