When we went to Mysore, the restaurant where we ate had the unusual toilet you see at the right. For the many times I had to squat in the woods while camping, I was thankful because I had to do that with this contraption. The corrugated sides are where you place your feet, then you get situated, squat and go. They also provided a faucet and pitcher for any additional cleanup that might be required.
Speaking of going. Many people traveling on the road didn't think anything about pulling over, unzipping and letting it fly! Without trying to be discrete or worrying about gender. When you had to go, you go and it doesn't matter where.
I have quite a few NICE photos to post and will post over the next couple of days. I have moved their home to a place that allows for better description interface. Until then!
