6-8 rolls of toilet paper, all premium branded.
If they are using that much a week, just imagine what their food bills must be.
Maybe they have digestive issues? I probably go through 4-6 rolls of tp per week just myself. Maybe they are just wasteful, but how do you go through tp other than using it for it's designated purpose?
Before I got married, toilet paper was a cheaper alternative to tissue paper (I guess you pay extra to have them pre-cut the squares for you?). Women also use it to wad up around tampons, possibly for makeup related things, etc.
Anyways, how much do you poop? 1 roll per day implies like hourly pooping, right?
When I feel perfectly fine and normal, like 4-6 times per day. If i'm having issues, maybe 10 or so.
With small kids, you can go through a load of TP if you don't set out the three-squares rule early on. Use three squares, wipe, fold in half, repeat. If there is still brown, get three more squares. Also, my first wife would grab the first square on the roll, then mummify her whole hand, tear it off the roll, wipe once, repeat. I was forever buying TP and unclogging toilets. Technique matters as much as frequency!
I have a friend who does that too, we used to be roommates, but it would be for blowing his nose once. He walks into the bathroom, wraps his hand around so there's no way he could get mucus on his hand, blows his nose, throws it in the toilet. If he has to blow again, or wipe off whatever is left (for whatever reason he couldn't have folded it for that purpose), he rewraps his hand. His Paper towel usage is similar, grabs three or for together, wipes one thing, throws away the bunch.
Now, to see how destructive this habit can be one day he was upstairs to take a shower in his house (now married with two kids), blows his nose with the bunch of toilet paper, throws it in the toilet and flushes, then goes to take a shower. 10 or 15 minutes later he feels cold water on his feet and finds that the wad of toilet paper had plugged his toilet and it has now flooded enough to come over the 3-4 inches of barrier for his shower and is making it's way down the walls, over the carpet, everywhere. He had to file an insurance claim and get a lot of work done to his house.
His solution for this, though, was that he went and bought a toilet, I believe a Toto, that has youtube videos of being able to suck down tennis balls.
In contrast my wife and I go through maybe one roll of paper towels in a month, including hand washing all of our dishes and using paper towels to dry. We get the style that are half sheets so you don't end up with more towel than you need. We do have tissues in a box, but are equally as frugal with them. Really, we buy a pack from Costco of each of them maybe once or twice a year.
