Blame social media. Video after video of people stacking their carts with TP! Social media and idiots....that’s the problem.
Coming from a hurricane prone area where after a storm, supplies could be short, we knew we could use a wet washcloth & double wash those things! Not the best substitute but it is a solution!
Nothing new. Back in the day Johnny Carson made a joke about tp and it started a run on it for a while at least.
