TBF, the many people who don't keep a lot of extra stock in the house probably got caught out early on even as the usage was going up a lot. So there probably are genuinely people who need it at this point and they're buying more than they usually do. (And, yes, a lot of people who are in the store for other reasons may well grab a package of TP even if they don't really need it and wouldn't normally have bought it.)
