Dear RR ji,
You would be surprised to know that I can eat on the floor sitting sideways...I always ate like that even as a child.
When I worked in rural Malaysia I always was invited for muslim functions where all woman are supposed to sit on the floor and eat from one huge plate.
Since I was veg..my plate would be different and for Malays its a big no no for woman to sit cross legged on the floor.
So one sits sideways and eats..its not too hard..it easy...left hand is placed on floor at times to support body.
So when I eat Banana leaf food on floor I eat sideways cos I dont like sitting cross legged in public.
The only time I sit cross legged is when I am exercising alone.
