Whilst traveling the length of India, the train would come to a halt every so often in an open field whereupon the aged and young alike would disembark for a few minutes, with nothing but an old baked bean can,( or something similar), with water in it and a piece of string for a handle.
The Indian custom is to wipe with the left and eat with the right, literally, often without utensils. It is the same in town, when using the squat style toilets, as the drains simply cannot handle vast amounts of paper.
After seeing the disgusting mess over here behind trees of paper, soiled paper at that, blowing in the wind, I believe the Indians to be far more civilized than a lot of westerners.
