I probably should take a step back and scratch the part about less developed country. I was actually referring to China which isn't really a developing country anymore, and haven't been to any developing country so I don't know what type of plumbing they have. A lot of the people in China use waste basket for toilet paper. However, the toilet and plumbing (except for those squatting toilets which is basically a hole in the floor) are not much different than what we have in the US and can more than handle toilet papers. This may be different 10 or 15 years ago and that's why many people are just used to waste basket. I don't know. All I know is that based on my observation, waste basket isn't just found in Sochi but used around the world including the US despite the toilets being able to handle toilet papers.
