It really is one of the great debates: What is the right way to hang a toilet paper roll? Research shows you use less paper when you drape the end over the top of the roll, simply because it’s easier to see. You also don’t have to reach as far to grab the paper. Also, it’s more sanitary to pull from the front since you’re not touching the wall and leaving germs as you would when pulling from the back. And finally — and this is the biggie — hotels can’t be wrong.
