I use a lot more TP when I am not at home, because I am not paying for it.

I have for some odd reason really paid attention to this because I noticed that at work I use about 240% more than at home. This is due to the fact that the quality is so bad for the stuff at work that I tend to bundle it up.
I am real curious at the cost variance between high quality and low quality and if it would be less expensive to use a mid-high grade and reduce the volume. Maybe I am the only one that does this?

One sheet or square is roughly 4" X 4". That makes 228" or 19' of toilet paper a day. 912 square inches or 6.33333 square feet... that's a lot of toilet paper...
