DISAPPOINTING. It's okay, her refusal of the drinks he's pushing just means he's getting drunker that much faster and he just keeps offering like maybe she'll change her mind. Why not when the only consequence is more drink for him? He'll be doing all her celebrating for her without complaint, no worries.
He is still pretty bent on trying to build her interest in the wave pool when he notices his lucky coin still around her neck and suddenly changes his mind without explanation. Nah, forget the wave pool, it's lame. What are those bungalows about??
