@Lordyaswas,
Kids in bathrooms, how hard is it to replace the roll. I was always hounding my teenager to replace the roll when it was empty, he apparently was not tuned to pick up my frequency. On one particular day, after finding 2 bathrooms without toilet paper, and also finding 8 cans of soda opened but not empty, when son arrived, asked what were we having for dinner, I told him and then I said "oh, by the way, I had the engineers in today", now I have his attention, he said what did they do?, so I told him I had to have fresh rolls of toilet paper replaced in two bathrooms and search for and dispose of the 8 semi-full cans of flat soda scattered around the house.
It worked for awhile.
