In 2000, I taught a software course in Bangalore, Karnataka (India). (Sorry, we’re now supposed to call it Bengaluru.) The class was held in a large lecture hall seating 200–300 people on the campus of Visvesvaraya Technological University. There was no plumbing in the entire building. The toilet facilities consisted of a small shed about 100 yards away with a single hole-and-pole (the pole for holding onto while depositing your excretions in the hole). I quickly learned to save my business for the hotel at night. Luckily I never developed Delhi Belly, or I know not what I would have done.
