We were on a tour of India some years ago, after a couple of days one man tried to get everyone to complain becuase we hadn't been told it would be hot, dusty/dirty, lots of bugs and we would see a lot of poverty. He demanded to be repatriated, a full refund and compensation for his distress! This was prior to digital cameras and his poor wife had to stand at the side of him to make notes of when, where and what settings the picture was take at.
The company very generously offered to take him to the final stop and would spend 12 days there, he insisted his wife joined him too.
When we joined them eventually they were barely speaking and he blamed the company!
