Question: how hard is it to eat with your mouth closed?

I understand if you have a nasal condition and occasionally have to breathe whilst eating, but is there any need to roll the food round in your mouth, stick your tongue out, just a little, at the end of each rotation, and then make a little snapping sound with your tongue. On top of that, is there any reason to take about 35 minutes to eat a tray of rice and curry whilst doing this. I could put up with it for the 5 mins it would take any normal person to gulp it down, but 35 mins!? Oh, and how about a bit of variety? This guy gets exactly the same thing delivered every day.

God I need a holiday.
