Still on the flight

It is already 12 at new York time, but is only 9 in sf. I am getting hungry, but it is only time for breakfast.
Maybe I should ask for some more snack? I have already finshed 4 cups of drinks and gone to restroom for 3 times. And ppl sit beside me don’t move at all! Don’t they feel dry? Maybe Americans are just born to be too strong. The kid sits beside me wears short pants. It is winter!!
