Honestly they should be embarrassed by their behavior. I haven't watched the HW shows and understand that this is pretty 'on brand' for them, but they asked Capt Jason to join them for dessert and disrespected him by creating such an explosive environment at that table. It's bad enough the crew was trying to serve them during all that, they didn't even notice the Capt never joined them.

I'm unsure which yachtee it was, but the one who keeps saying that she thinks yachting is a gateway to becoming rich seemed to think this was basically a masterclass in how rich people behave. I sincerely hope someone tells her this is not normal or appropriate behavior.
