Watching ‘ Triangle of Sadness’ and some sea-sick, fine-dining passengers on a luxury yacht expelling remnants of gastronomy into beautifully-carved bowls of gold whilst fumbling to maintain an air of elegance and dignity— I thought— this must be the funniest thing I’ve seen this year until the camera pans to what looks like a squeegee cleaning a window, quite unfazed by incessant splashes of turbulent sea water— a job has to be done and it shall be carried out regardless.
