I shopped at Costco this morning just after it opened. As I’m entering the store I see multiple people leaving with carts carrying a huge pack of TP. Some also had paper towels.
As I was shopping I saw a lot more carts with a big pack of TP (customers are limited to one.) I have been there frequently in the past couple of months and I did not observe this in other trips.
I think normies are starting to wake up about shortages!
Just after WW2, in the UK I recall using squares of newspaper. It didn't flush easily and left my ass streaky black from the ink.
Muslims use their left hand - allegedly (yuk).
I think that I would resort to the shower head (if no water shortage) and/or a bucket of water and a soft cloth.
