If you are worried about this you might want to consider whether you have a healthy degree of concern about hygiene and bacteria. It could be worth speaking with a therapist.
I am not personally turned off by the hygiene of toilet paper rolls, but I think any rational adult's Overton Window should accommodate those who are. Your condescension is grossly unwarranted.
You don't have to be Adrian Monk to recognize that toilets are unsanitary.
I'm not sure where you got condescension from - I was going for genuine concern. Being irrationality concerned about hygiene is a warning sign for conditions like obsessive compulsive disorder.
Eh, it got a chuckle and eye roll outta me so I didn't mind.
And fwiw, I don't really care either wherever people use them for whatever they want, I am just still confused why people would want to use paper (sourced from leftover toilet utensils), which is notorious for being basically un-cleanable... as food storage, but to each their own.
I'm surprised how many people hate me for such (imo) mellow statement though
I don't really think anyone other than OCD/germaphobes thinks about toilet paper rolls in that way and it's certainly not "notorious". I'm pretty sure the general sentiment is that it's a perfectly benign material, often given to kids to play and craft with.
The same thing happened with that episode of mythbusters about the toilet ploom from flushing. A bunch of OCD/germaphobes lost their minds and have not stopped thinking about it since. Meanwhile the rest of society gave a collective shrug and couldn't even be bothered to move their toothbrush brush to another room or close the toilet lid while flushing.
This isn't a food storage thing, but I think I see where you got that idea from the photos in the link. He's showing the types of paperboard that work with his system. Old cereal boxes, coffee filter boxes, etc.
